Product details
Overview
MAX1030BEEG+ from Maxim Integrated is a 10-bit, 300ksps serial analog-to-digital converter with integrated temperature sensor (±0.7°C accuracy at +25°C), 16-entry FIFO, internal 4.096V reference, and true differential track-and-hold. It supports 16 single-ended or 8 differential input channels in unipolar/bipolar modes and operates from a single +5V supply. It is used in industrial control systems for multichannel voltage and temperature monitoring with minimal host interface overhead.
For engineers reviewing the MAX1030BEEG+ datasheet, MAX1030BEEG+ pinout, MAX1030BEEG+ application, or MAX1030BEEG+ equivalent, this page delivers verified technical context, real-world design meaning of key specs, package-validated pin functions, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The MAX1030BEEG+ implements a fully differential successive-approximation register (SAR) ADC core with on-chip track-and-hold, supporting both single-ended and true differential acquisition. Its internal oscillator enables autonomous scan mode operation without external timing control in clock modes 00/01/10.
It integrates a dedicated temperature-sensing path using the same internal reference and SAR architecture, delivering 1/8°C resolution in two's complement format. The 16-deep FIFO buffers conversion results-including temperature data-enabling burst acquisition without serial bus contention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - Provides 1024 discrete output codes; sufficient for precision system supervision where <0.1% full-scale resolution is required. |
| Sampling Rate | 300ksps max (external clock) - Enables capture of signals up to 100kHz full-linear bandwidth; supports undersampling of higher-frequency transients. |
| INL / DNL | ±1 LSB - Guarantees monotonicity and no missing codes across –40°C to +85°C; critical for closed-loop control feedback integrity. |
| Internal Reference | 4.096V ±2.0% (Grade B), ±20ppm/°C TC - Delivers stable scaling without external reference components; eliminates layout sensitivity and BOM cost. |
| Temperature Sensor Accuracy | ±0.7°C at +25°C, ±1.2°C over –40°C to +85°C - Enables direct board-level thermal monitoring without calibration in medical or industrial environments. |
| Supply Current | 2.3mA at 300ksps (internal ref), 0.2–5μA shutdown - Supports low-power operation in battery-backed or energy-constrained data loggers. |
| Digital Interface | 10MHz SPI/QSPI/MICROWIRE-compatible 3-wire - Compatible with standard microcontroller peripherals; supports CPOL/CPHA = 0 or 1 for flexible host integration. |
Pinout & Package
The MAX1030BEEG+ is packaged in a 28-pin 5mm × 5mm TQFN with exposed pad (EP), RoHS-compliant and lead-free. The exposed pad must be soldered to a GND plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN0–AIN15 | Analog Input Channels | 16 configurable inputs; each can be assigned as single-ended or paired differentially (e.g., AIN0/AIN1); AIN12–AIN15 available only on MAX1030. |
| REF+/REF− | Reference Inputs | REF+ accepts 1.0V to VDD+50mV; REF− serves as negative reference or analog input (AIN14); internal 4.096V ref eliminates need for external reference unless higher precision is required. |
| CNVST/AIN15 | Conversion Start / Analog Input | Active-low hardware trigger for conversions; when configured as CNVST, AIN15 is disabled-prevents accidental channel conflict during hardware-triggered acquisition. |
| SCLK, DIN, DOUT, CS | Serial Interface | Standard 3-wire SPI-compatible interface; DOUT updates on SCLK falling edge; CS enables serial port and controls DOUT tri-state behavior. |
| EOC | End-of-Conversion Flag | Active-low open-drain output; asserts after conversion completion in clock modes 00/01/10; remains high in externally clocked mode (11) to avoid contention. |
| VDD, GND, EP | Power & Ground | VDD = +4.75V to +5.25V; EP must be connected to GND for thermal dissipation and noise reduction-critical for ADC SNR performance. |
Key Features
| Feature | Design Value |
|---|---|
| 16-entry FIFO buffer | Stores up to 16 ADC results plus one temperature reading-enables background scanning while host processes prior data, reducing MCU polling overhead. |
| True differential track-and-hold | Supports 8 differential pairs (e.g., AIN0/AIN1) with common-mode rejection; eliminates DC offsets and noise in noisy industrial signal chains. |
| Internal temperature sensor | Integrated diode-based sensor with ±0.7°C accuracy at +25°C-provides board-level thermal awareness without external sensors or calibration. |
| AutoShutdown™ mode | Reduces supply current to ≤5μA during idle periods-extends battery life in portable data loggers and remote monitoring nodes. |
| Scan mode & internal averaging | Configurable multi-channel sequencing and per-result averaging (up to 4×)-improves effective resolution and noise immunity in slow-varying process signals. |
Applications
| Industrial Process Monitoring | Patient Vital Sign Acquisition |
|---|---|
Use Scenario: Continuous logging of thermocouple outputs, pressure transducer voltages, and ambient temperature in PLC-based factory automation cabinets. IC Role / Device Role / Timing Role: Multichannel ADC with integrated temp sensor performs synchronized voltage and board-temperature sampling every 10ms via internal clock mode 00. Use Value: Eliminates need for separate temperature IC and external reference; 16-channel count reduces channel multiplexer count and PCB area in dense I/O modules. |
Use Scenario: Simultaneous acquisition of ECG leads, respiration sensor output, and patient skin temperature in portable bedside monitors. IC Role / Device Role / Timing Role: Single-chip solution digitizing 8 differential biopotential channels and local thermal context-supports real-time waveform display and alarm thresholds. Use Value: Bipolar differential mode rejects common-mode interference from AC mains; internal FIFO prevents data loss during USB bulk transfer latency. |
| Data Logging in Harsh Environments | Energy Meter Subsystem Monitoring |
Use Scenario: Battery-powered environmental sensor node measuring soil moisture, solar irradiance, and enclosure temperature across –40°C to +85°C range. IC Role / Device Role / Timing Role: Low-power ADC wakes periodically via timer interrupt, acquires all 16 channels + temperature, then enters AutoShutdown™ until next cycle. Use Value: 2.3mA active current and sub-5μA shutdown enable >1-year battery life on 2000mAh Li-ion; internal reference ensures consistent scaling despite voltage droop. |
Use Scenario: Secondary monitoring path in smart meters tracking auxiliary voltages (battery backup, RTC supply), heatsink temp, and tamper detection signals. IC Role / Device Role / Timing Role: Dedicated supervisory ADC offloads main metrology IC; uses CNVST-triggered single-shot mode to capture transient events like power fail. Use Value: Hardware CNVST pin allows deterministic sampling independent of SPI bus state-ensures capture of fast fault conditions without software delay. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit multichannel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8320IDR | 16-bit, 100ksps, no internal ref or temp sensor; SPI-only interface; requires external reference and driver. | Better resolution for precision instrumentation; lacks integrated temp sensing and FIFO-requires host MCU coordination for multi-channel sequencing. | Select when 16-bit resolution and lower noise floor outweigh need for integrated features; not drop-in due to pinout, voltage, and feature mismatch. |
| AD7923BRUZ | 12-bit, 1MSPS, 8-channel, no FIFO or temp sensor; internal reference selectable (2.5V/4.096V); SPI-compatible. | Higher speed and resolution for dynamic signal capture; no temperature capability or FIFO-unsuitable for autonomous thermal-aware logging. | Choose for high-speed voltage-only acquisition where thermal monitoring is handled separately; differs in channel count, packaging (20-TSSOP), and missing FIFO/temp functions. |
Compared with MAX1030BEEG+, ADS8320IDR trades integration for resolution and AD7923BRUZ trades autonomy for speed-neither replicates the combined 16-channel count, FIFO buffering, and calibrated temperature sensing in a single +5V device.

FAQ
What is the maximum number of analog input channels supported by the MAX1030BEEG+?
The MAX1030BEEG+ supports up to 16 single-ended analog input channels (AIN0–AIN15) or 8 true differential pairs (e.g., AIN0/AIN1 through AIN14/AIN15). This channel count is exclusive to the MAX1030 variant-MAX1028 offers 12 single-ended/6 differential channels, and MAX1026 offers 8/4. All channels are software-configurable via the setup register.
Does the MAX1030BEEG+ require an external reference voltage?
No, the MAX1030BEEG+ includes an internal 4.096V reference with ±2.0% initial accuracy and ±20ppm/°C temperature coefficient-sufficient for most industrial and medical applications. An external differential reference can be applied via REF+ and REF− pins if tighter tolerance or custom scaling is needed, but doing so disables the internal reference and temperature sensor functionality.
How does the FIFO in the MAX1030BEEG+ improve system-level data acquisition?
The 16-entry FIFO in the MAX1030BEEG+ stores complete conversion results-including optional temperature readings-allowing the host MCU to initiate a multi-channel scan and retrieve results later without continuous bus occupation. This decouples acquisition timing from processing timing, preventing data loss during host interrupts or communication delays, and simplifies firmware for burst-mode logging.
Can the MAX1030BEEG+ perform simultaneous sampling across multiple channels?
No, the MAX1030BEEG+ uses a single SAR ADC core with a multiplexed input stage-it performs sequential sampling, not true simultaneous sampling. However, its fast 3.5μs acquisition time and 300ksps maximum rate enable tightly spaced sequential conversions (e.g., 16 channels in ~53μs), which approximates simultaneity for low-bandwidth signals like temperature or DC process variables.
What is the operating temperature range specified for the MAX1030BEEG+?
The MAX1030BEEG+ is specified for operation from –40°C to +85°C, matching the "E" grade suffix in its part number. This extended industrial temperature range ensures reliable performance in harsh environments such as factory floors, outdoor metering enclosures, and automotive under-hood telemetry modules-without derating or additional thermal management.
