Product details
Overview
MAX1030BCEG+ 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 MAX1030BCEG+ datasheet, MAX1030BCEG+ pinout, MAX1030BCEG+ application, or MAX1030BCEG+ equivalent, this page delivers verified technical context, real-world design meaning of key specs, package-validated pin functions, and two confirmed alternative parts - all grounded in the official MAX1030 datasheet Rev 4 (2011) and Maxim's product documentation.
Technical Context
The MAX1030BCEG+ implements a fully differential successive-approximation register (SAR) ADC architecture with on-chip track-and-hold, supporting both single-ended and true differential acquisition. Its internal oscillator enables autonomous conversion timing in clock modes 00/01/10, while mode 11 accepts external SCLK up to 10MHz for precise 300ksps sampling.
It integrates a dedicated temperature-sensing path using the same internal reference and SAR core, delivering 1/8°C resolution in two's complement format. The 16-deep FIFO buffers conversion results and temperature readings independently, decoupling data acquisition from serial bus activity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - delivers 1024 discrete output codes; sufficient for precision industrial sensing without oversampling complexity |
| Sampling Rate | 300ksps maximum - supports real-time capture of signals up to 100kHz full-linear bandwidth |
| INL / DNL | ±1 LSB - guarantees monotonicity and no missing codes across –40°C to +85°C, critical for closed-loop control |
| Internal Reference | 4.096V ±1.7% (±20ppm/°C TC) - provides stable scaling without external reference components |
| Temperature Sensor Accuracy | ±0.7°C at +25°C, ±1.2°C over full range - enables system-level thermal compensation without calibration |
| Supply Current | 2.3mA at 300ksps - enables low-power operation in battery-backed or energy-constrained monitoring nodes |
| Digital Interface | 10MHz SPI/QSPI/MICROWIRE-compatible 3-wire - interoperable with standard microcontroller peripherals without protocol translation |
Pinout & Package
The MAX1030BCEG+ is housed in a 28-pin 5mm × 5mm TQFN package with exposed pad (EP), RoHS-compliant and lead-free. Thermal performance is enhanced by direct EP-to-GND connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN0–AIN15 | Analog Input Channels | 16 configurable inputs; support single-ended (GND-referenced) or true differential pairs (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; enables external differential reference or extended input ranges |
| CNVST/AIN15 | Conversion Start / Analog Input | Active-low hardware trigger for conversions; dual-function pin - configured as CNVST via setup register, disabling AIN15 use |
| SCLK, DIN, DOUT, CS | Serial Interface | Standard 3-wire SPI-compatible interface; DOUT updates on SCLK falling edge; CS enables high-impedance DOUT when high |
| EOC | End-of-Conversion Flag | Active-low open-drain output; asserts low after conversion completion; behavior varies by clock mode (e.g., per-channel in mode 01) |
| VDD, GND, EP | Power & Ground | VDD = +5V ±5%; 0.1µF bypass capacitor required; EP must be soldered to GND plane for thermal and electrical stability |
Key Features
| Feature | Design Value |
|---|---|
| 16-entry FIFO buffer | Stores up to 16 ADC results plus one temperature reading - eliminates serial bus contention during burst acquisition sequences |
| Internal temperature sensor | ±0.7°C accuracy at +25°C, 1/8°C resolution - enables on-chip thermal monitoring without external sensors or calibration |
| True differential track-and-hold | Supports 8 differential channel pairs (e.g., AIN0/AIN1) with common-mode noise rejection - improves SNR in noisy industrial environments |
| Scan mode & internal averaging | Configurable multi-channel scan with programmable averaging (1–8 samples) - reduces noise in low-SNR sensor interfaces |
| AutoShutdown™ | Reduces supply current to ≤5µA in shutdown - extends battery life in portable data loggers between measurement cycles |
Applications

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 |
|---|---|---|---|
| ADS7953IRHBT | 12-bit resolution, 1MSPS, SPI interface, no integrated temp sensor, requires external reference | Better resolution/speed but lacks on-chip temperature sensing and reference - needs additional components for same functionality | Select when higher resolution and speed outweigh integration benefits and board space constraints |
| AD7923BRUZ | 12-bit, 1MSPS, 8-channel, no FIFO, no temp sensor, internal reference only (2.5V), SPI-compatible | Lacks FIFO buffering and temperature sensing; limited to 8 channels - insufficient for 16-channel or thermal-aware designs | Choose for cost-sensitive, lower-channel-count applications where FIFO and temp sensing are not required |
Compared with ADS7953IRHBT and AD7923BRUZ, the MAX1030BCEG+ trades raw speed and resolution for unique integration - its on-chip FIFO, temperature sensor, and 4.096V reference enable compact, self-contained monitoring in space-constrained industrial and medical systems without external support circuitry.

FAQ
What is the operating temperature range for the MAX1030BCEG+?
The MAX1030BCEG+ is specified over the extended industrial temperature range of –40°C to +85°C. This rating applies to all electrical characteristics including INL/DNL, reference voltage drift, and temperature sensor accuracy. The device maintains ±1 LSB linearity and ±1.2°C temperature measurement error across this full range, making it suitable for harsh-environment deployments like factory automation and outdoor instrumentation.
Does the MAX1030BCEG+ require an external reference voltage?
No, the MAX1030BCEG+ includes a factory-trimmed internal 4.096V reference with ±20ppm/°C temperature coefficient, eliminating the need for an external reference in most applications. An external differential reference can be applied via REF+ and REF− pins if higher precision or custom scaling is required, but doing so disables the internal reference and temperature sensor functionality - the MAX1030BCEG+ always uses its internal reference for temperature measurements.
How many analog input channels does the MAX1030BCEG+ support in differential mode?
The MAX1030BCEG+ supports eight true differential input pairs: AIN0/AIN1, AIN2/AIN3, AIN4/AIN5, AIN6/AIN7, AIN8/AIN9, AIN10/AIN11, AIN12/AIN13, and AIN14/AIN15. This is enabled by its 16-input architecture - the only member of the MAX1026/MAX1028/MAX1030 family with full 16-channel support. Differential mode rejects common-mode noise and enables bipolar input ranges of ±VREF/2, which is essential for sensor interfaces like bridge circuits and isolated current sensing.
Can the MAX1030BCEG+ perform simultaneous sampling across multiple channels?
No, the MAX1030BCEG+ does not support true simultaneous sampling. It uses a single SAR ADC core with a multiplexed analog front-end and track-and-hold circuit, performing sequential conversions across selected channels in scan mode. However, its 300ksps maximum sampling rate and 16-entry FIFO allow rapid sequential acquisition - for example, scanning all 16 channels in under 54µs - which approximates simultaneity for low-bandwidth signals (<10kHz) in applications like motor phase current monitoring.
What package type is used for the MAX1030BCEG+?
The MAX1030BCEG+ is supplied exclusively in a 28-pin 5mm × 5mm TQFN package with exposed pad (EP). This package offers superior thermal performance and smaller footprint than the QSOP variants used for MAX1026/MAX1028. The exposed pad must be soldered to a solid GND plane for optimal thermal dissipation and electrical stability - omission risks increased junction temperature and degraded INL performance at high sampling rates.
