Product details
Overview
The MAX11617EEE+T from Maxim Integrated is a 12-bit, 12-channel I²C-compatible analog-to-digital converter with internal 2.048V reference, single-supply operation (2.7V–3.6V), 94.4ksps max sampling rate, and ultra-low 670µA active current - designed for precision sensor data acquisition in space-constrained, battery-powered systems such as handheld medical instruments and solar-powered remote monitoring.
For engineers reviewing the MAX11617EEE+T datasheet, MAX11617EEE+T pinout, MAX11617EEE+T application, or MAX11617EEE+T equivalent, this page delivers verified electrical specs, QSOP-16 package details, I²C timing compliance (Fast Mode/High-Speed Mode), unipolar/bipolar software configuration, and real-world use cases - all validated against Maxim's official datasheet Rev 4 (19-4561).
Technical Context
The MAX11617EEE+T employs successive-approximation architecture with fully differential track-and-hold circuitry, supporting both single-ended (12-channel) and differential (6-channel) input modes. Its internal 2.048V reference and programmable BIP/UNI bit enable precise unipolar (0–VREF) or bipolar (±VREF/2) measurement ranges.
It integrates an I²C slave interface compliant with Fast Mode (400kHz) and High-Speed Mode (1.7MHz), with configurable SCL timing, acknowledge-handling logic, and auto-shutdown reducing current to <1µA at low throughput - all managed via setup/configuration registers without external clocking components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - delivers 4096 discrete output codes for high-fidelity signal digitization in sensor and control loops. |
| Input Channels | 12 single-ended or 6 fully differential - enables simultaneous multi-sensor monitoring (e.g., temperature, pressure, voltage rails) without external multiplexers. |
| Sampling Rate | 94.4ksps maximum - supports dynamic signal capture up to ~3MHz full-power bandwidth for transient event analysis. |
| Supply Voltage | 2.7V to 3.6V - compatible with Li-ion, coin-cell, and regulated 3.3V systems without level-shifting. |
| Reference Voltage | Internal 2.048V ±0.08V (25°C), 25ppm/°C TC - provides stable scaling for ratiometric measurements without external reference ICs. |
| INL / DNL | ±1 LSB integral nonlinearity, ±1 LSB differential nonlinearity - ensures monotonicity and <0.024% full-scale error across temperature. |
| I²C Clock Support | Up to 1.7MHz High-Speed Mode - reduces conversion readout latency by >4× vs. standard 100kHz I²C, critical for real-time feedback control. |
Pinout & Package
The MAX11617EEE+T is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 1.0mm height) with industry-standard lead pitch (0.635mm), optimized for automated assembly and thermal performance in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–12 (AIN0–AIN11) | Analog Input Channels | 12 individually selectable single-ended inputs or 6 differential pairs; software-configurable for unipolar/bipolar mode via setup register. |
| 13 (SCL) | I²C Serial Clock Input | Accepts master-generated clock up to 1.7MHz; controls timing of address/data transfer and internal conversion clock synchronization. |
| 14 (SDA) | I²C Serial Data I/O | Bidirectional open-drain line for read/write of configuration bytes, conversion results, and status flags; requires external pull-up. |
| 15 (GND) | Analog/Digital Ground | Common reference for analog inputs, digital interface, and internal reference; must be low-impedance and separated from noisy digital return paths. |
| 16 (VDD) | Positive Supply | 2.7V–3.6V single supply powering analog core, digital logic, and internal reference; requires local 0.1µF ceramic bypass to GND. |
Key Features
| Feature | Design Value |
|---|---|
| AutoShutdown™ | Reduces supply current to <1µA between conversions - extends battery life in intermittent-sampling applications like environmental loggers. |
| Software-Configurable Input Mode | Single-ended/differential and unipolar/bipolar selection via setup byte - eliminates hardware rework when adapting to new sensor types or signal polarities. |
| Internal FIFO with Channel-Scan Mode | Automatically cycles through up to 12 channels and buffers results - simplifies firmware for multi-point monitoring without host CPU intervention per sample. |
| Low Source Impedance Tolerance | Accurate sampling with ≤1.5kΩ source impedance - avoids need for external op-amp buffers in most resistive sensor interfaces (e.g., RTDs, potentiometers). |
| Robust Analog Input Protection | Clamps inputs to GND–VDD ±0.3V with internal diodes - withstands ESD and overvoltage transients common in industrial field wiring. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit, multi-channel, I²C ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7953IRHBT | 12-bit, 16-channel, SPI interface only; no internal reference; requires external 2.5V ref; 1MSPS max rate. | Requires SPI host and external reference design; higher speed but incompatible I/O protocol. | Select if system already uses SPI infrastructure and needs >94ksps throughput; avoid if I²C bus is constrained or reference integration is required. |
| MCP3208-CI/P | 12-bit, 8-channel, SPI interface; internal 2.56V ref; 100ksps; no AutoShutdown; 5V-only supply (4.5–5.5V). | Lacks I²C compatibility, 12-channel support, and sub-1µA shutdown - unsuitable for 3.3V battery systems. | Consider only for legacy 5V designs where SPI is preferred and channel count ≤8; not drop-in for MAX11617EEE+T. |
Compared with ADS7953IRHBT and MCP3208-CI/P, the MAX11617EEE+T uniquely combines I²C compatibility, integrated 2.048V reference, 12-channel flexibility, and <1µA shutdown - making it optimal for space- and power-sensitive embedded systems where bus simplicity and reference autonomy are critical.

FAQ
What is the operating supply voltage range for the MAX11617EEE+T?
The MAX11617EEE+T operates from a single supply of 2.7V to 3.6V. This range is strictly defined for the MAX11613/MAX11615/MAX11617 variants and is incompatible with 4.5V–5.5V supplies used by the MAX11612/MAX11614/MAX11616 family members. Exceeding 3.6V may damage the device.
Does the MAX11617EEE+T support differential input mode?
Yes, the MAX11617EEE+T supports fully differential input mode across 6 channel pairs (e.g., AIN0–AIN1, AIN2–AIN3). This is enabled via the SGL/DIF bit in the configuration byte. In differential mode, the BIP/UNI bit further selects unipolar (0 to VREF) or bipolar (±VREF/2) full-scale ranges.
What is the I²C slave address of the MAX11617EEE+T?
The factory-programmed I²C slave address for the MAX11617EEE+T is 0110101 (0x35 in 7-bit format). The least significant bit (R/W) determines direction: 0x6A for write, 0x6B for read. This address is fixed and cannot be altered via pins or registers.
Can the MAX11617EEE+T use an external reference voltage?
Yes, the MAX11617EEE+T accepts an external reference voltage from 1V to VDD applied to the AIN11/REF pin. When using external reference, the internal 2.048V reference is disabled. Performance remains specified across temperature, but reference stability and noise become system-dependent.
How does AutoShutdown™ reduce power consumption in the MAX11617EEE+T?
AutoShutdown™ powers down the MAX11617EEE+T's analog core and reference between conversions, reducing supply current to less than 1µA at low throughput rates (e.g., <1ksps). This feature is automatic and requires no host command - it activates whenever the I²C bus is idle and no conversion is pending.
