Product details
Overview
MAX1083AEUE from Maxim Integrated is a 10-bit, 4-channel serial analog-to-digital converter (ADC) with integrated track/hold, multiplexer, and internal +2.5V reference. It operates from a single +2.7V to +3.6V supply, supports software-configurable unipolar/bipolar and single-ended/pseudo-differential inputs, and delivers 300ksps sampling rate-optimized for battery-powered instrumentation and portable data acquisition.
For engineers reviewing the MAX1083AEUE datasheet, MAX1083AEUE pinout, MAX1083AEUE application, or MAX1083AEUE equivalent, key selection criteria include its 300ksps throughput, ±0.5 LSB INL, 2.5µA full power-down current, TSSOP-16 package compatibility, and SPI/QSPI/MICROWIRE serial interface timing compliance at 4.8MHz.
Technical Context
The MAX1083AEUE uses successive-approximation register (SAR) architecture with an on-chip track/hold amplifier and 4:1 analog multiplexer. Its conversion cycle requires 16 SCLK periods at 4.8MHz, yielding a guaranteed 300ksps sampling rate under specified conditions (VDD = +2.7V to +3.6V, TA = –40°C to +85°C).
It features dual power domains (VDD1/VDD2), a reference-buffer amplifier with ±1.5% adjustment range via REFADJ, and four programmable power modes-including FULLPD (2µA typ) and FASTPD (0.9mA typ)-with automatic wake-up on serial interface activity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit SAR ADC with no missing codes over temperature |
| Sampling Rate | 300ksps maximum - defines real-time signal capture capability for sub-150kHz bandwidths |
| INL | ±0.5 LSB - ensures monotonicity and <0.05% full-scale linearity error in calibrated systems |
| Supply Range | +2.7V to +3.6V single supply - enables direct integration into 3.3V logic and Li-ion battery systems |
| Full Power-Down Current | 2µA typical - extends battery life in sleep-mode data loggers between acquisitions |
| Reference | Internal +2.500V ±10mV (±0.4%) - eliminates external reference component while maintaining 10-bit accuracy |
| Operating Temperature | –40°C to +85°C - qualified for industrial and medical embedded environments |
Pinout & Package
MAX1083AEUE is housed in a 16-pin TSSOP package (4.4mm × 5.0mm, 0.65mm pitch) with exposed pad for thermal enhancement. Pin functions are electrically validated per Maxim's 19-1690 Rev 0 datasheet and confirmed across production variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, VDD2 | Positive supply inputs | Dual-supply pins support low-noise analog and digital domain separation; must be tied together for single-supply operation |
| GND | Analog/digital ground reference | Common return for all analog inputs, reference, and digital I/O; critical for ±0.5 LSB offset stability |
| CH0–CH3, COM | Analog input channels and common | Supports 4-channel single-ended or 2-channel pseudo-differential acquisition; COM sets zero-code voltage |
| REF, REFADJ | Reference buffer output / adjustment | REF provides 2.500V ±10mV; REFADJ allows ±1.5% fine-tuning or disables buffer when pulled to VDD1 |
| SCLK, CS, DIN, DOUT, SSTRB | 4-wire serial interface | Fully SPI/QSPI/MICROWIRE-compatible; SSTRB enables TMS320 DSP synchronization without glue logic |
| SHDN | Hardware shutdown control | Active-low pin reduces supply current to 2µA; complements software power modes for layered power management |
Key Features
| Feature | Design Value |
|---|---|
| Software-configurable input mode | Runtime selection of unipolar/bipolar and single-ended/pseudo-differential via control byte - eliminates hardware rework for multi-sensor platforms |
| Integrated track/hold + multiplexer | On-chip T/H with 625ns acquisition time and 4:1 mux - removes external components and layout sensitivity in compact designs |
| Four-tier power management | Normal (2.5mA), REDP (1.3mA), FASTPD (0.9mA), FULLPD (2µA) - enables adaptive power scaling per acquisition duty cycle |
| Reference buffer with trim | ±1.5% REFADJ adjustment range and ±15ppm/°C TC - supports precision calibration without external DAC or op-amp |
| TSSOP-16 footprint | Industry-standard 16-pin thin shrink small-outline package - ensures drop-in replacement and PCB reuse across MAX1082/MAX1083 family |
Applications
| Portable Data Logging | Medical Instruments |
|---|---|

IC Role / Device Role / Timing Role: Single-supply ADC accepting bipolar inputs (±1.25V) referenced to internal 2.5V REF, with software-selectable channel sequencing. Use Value: Internal +2.5V reference with ±0.4% initial accuracy eliminates need for trimming; 300ksps rate supports fast response during calibration sweeps. | Use Scenario: Industrial 4–20mA loop-powered transmitter monitoring tank level, flow, and temperature in hazardous areas. IC Role / Device Role / Timing Role: 4-channel ADC digitizing isolated analog inputs from RTDs, thermocouples, and pressure transducers with common-mode rejection. Use Value: Channel-to-channel crosstalk <–78dB prevents cross-talk-induced drift in multi-parameter readings; –40°C to +85°C rating ensures reliability in uncontrolled cabinets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit serial ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 2.7V–5.25V supply; 200ksps; no internal reference; requires external REF or REFBUF | Lacks integrated reference and track/hold - increases BOM count and layout complexity | Choose when higher supply flexibility is needed and external reference is already present |
| MAX11131ETE+ | 12-bit resolution; 500ksps; +2.5V internal REF; same TSSOP-16 package | Higher resolution and speed but consumes 3.5mA in normal mode - less suitable for ultra-low-power logging | Choose when 12-bit precision and faster sampling justify 40% higher active current |
Compared with ADS7822U and MAX11131ETE+, the MAX1083AEUE uniquely balances 300ksps throughput, ±0.5 LSB INL, integrated reference, and 2µA shutdown - making it optimal for space-constrained, battery-operated systems requiring calibrated 10-bit performance without design overhead.

FAQ
What is the guaranteed sampling rate of the MAX1083AEUE under industrial temperature conditions?
The MAX1083AEUE guarantees a minimum 300ksps sampling rate across its full operating temperature range of –40°C to +85°C, verified with fSCLK = 4.8MHz, 50% duty cycle, and 16 clocks per conversion cycle per the official datasheet Electrical Characteristics table for MAX1083.
Does the MAX1083AEUE require an external reference voltage to operate?
No, the MAX1083AEUE does not require an external reference. It includes an internal +2.500V ±10mV reference with buffer amplifier; REFADJ allows ±1.5% adjustment. An external reference (1V to VDD) may be used only if the internal buffer is disabled by pulling REFADJ to VDD1.
How does the SHDN pin interact with the software power modes of the MAX1083AEUE?
The SHDN pin provides hardware-level shutdown independent of software modes: pulling SHDN low forces the MAX1083AEUE into full power-down (2µA), overriding any active software power setting. When SHDN is high, software modes (NORMAL, REDP, FASTPD, FULLPD) remain fully functional and accessible via serial interface commands.
What is the absolute maximum input voltage range for analog channels on the MAX1083AEUE?
The absolute maximum analog input voltage range for CH0–CH3 and COM is GND – 0.3V to VDD1 + 0.3V per Absolute Maximum Ratings. For accurate 10-bit conversion, inputs must stay within GND – 50mV to VDD1 + 50mV; exceeding this risks nonlinearity and code errors in the MAX1083AEUE.
Can the MAX1083AEUE interface directly with a TMS320-series DSP without level-shifting?
Yes, the MAX1083AEUE's SSTRB output and 3.3V-compatible digital I/O (DIN, DOUT, CS, SCLK) allow direct connection to TMS320-family DSPs operating at 3.3V logic levels. The SSTRB strobe pulse aligns with MSB decision timing, enabling synchronous capture without external logic or level translators.
