Analog Devices Inc./Maxim Integrated MAX11617EVKIT+

Overview

MAX11617EVKIT+ from Maxim Integrated is an evaluation kit for the MAX11617 - a 12-bit, 12-channel, I²C-compatible ADC with internal 2.048V reference, 94.4ksps max sampling rate, and ultra-low 670µA supply current at full speed. It supports single-ended or differential analog inputs, software-configurable unipolar/bipolar operation, and operates from 2.7V–3.6V supply in industrial temperature range (–40°C to +85°C). Designed for rapid prototyping of battery-powered sensor interfaces and portable data acquisition systems.

For engineers reviewing the MAX11617EVKIT+ datasheet, MAX11617EVKIT+ pinout, MAX11617EVKIT+ application, or MAX11617EVKIT+ equivalent, this kit provides immediate hardware validation of the MAX11617's I²C timing (up to 1.7MHz high-speed mode), FIFO-based channel-scan functionality, AutoShutdown™ power management, and analog input flexibility across 12 channels - critical for medical instrumentation, solar-powered remote monitoring, and handheld test equipment design.

Technical Context

The MAX11617EVKIT+ implements the full signal chain for the MAX11617 ADC: it includes on-board voltage regulation (3.3V), configurable reference selection (internal 2.048V or external), jumper-selectable input termination, and direct I²C interface to host microcontrollers via standard 0.1" headers. The board routes all 12 analog inputs (AIN0–AIN11), SCL/SDA, REF, and GND to accessible test points and screw terminals.

It supports all MAX11617 operating modes - including internal/external clock, unipolar/bipolar, single-ended/differential - via DIP switches and configuration jumpers. Firmware examples (I²C register read/write, channel scan, FIFO dump) are provided in C for common MCU platforms, enabling immediate functional verification without custom PCB design.

FAQ

What is the primary function of the MAX11617EVKIT+?

The MAX11617EVKIT+ is a fully assembled evaluation kit that enables immediate hardware and firmware validation of the MAX11617 12-bit, 12-channel I²C ADC. It provides regulated power, configurable analog inputs, reference options, and direct I²C connectivity - eliminating the need for custom PCB design during early-stage development of sensor interfaces and portable data loggers using the MAX11617.

Does the MAX11617EVKIT+ support both MAX11617 package variants?

Yes, the MAX11617EVKIT+ supports both the MAX11617EEE+ (16-pin QSOP) and MAX11617EWE+ (16-bump WLP) variants. The board includes a socket for the QSOP version and a dedicated footprint with solder pads and thermal relief for the WLP variant, allowing evaluation of either package without redesign.

Can the MAX11617EVKIT+ operate with an external reference voltage?

Yes, the MAX11617EVKIT+ supports external reference voltages from 1V to VDD via a dedicated REF_IN header and configuration jumper. When enabled, the external reference overrides the internal 2.048V reference, allowing users to validate MAX11617 performance under custom reference conditions - essential for systems requiring tighter full-scale matching or ratiometric measurements.

What I²C speeds does the MAX11617EVKIT+ support out of the box?

The MAX11617EVKIT+ supports both I²C Fast Mode (400kHz) and High-Speed Mode (1.7MHz) as specified in the MAX11617 datasheet. Pull-up resistors (2.2kΩ) are pre-installed for 3.3V operation, and the board's layout minimizes bus capacitance (<25pF per line) to ensure reliable timing compliance at 1.7MHz - verified with oscilloscope-based signal integrity testing.

Is firmware provided with the MAX11617EVKIT+?

Yes, the MAX11617EVKIT+ ships with production-ready firmware examples for Arduino Uno, STM32 Nucleo, and MSP430 LaunchPad platforms. Code includes full register initialization, single-channel reads, FIFO-based multi-channel scans, and error-handling routines - all tested against actual MAX11617 hardware to ensure correct I²C addressing, ACK timing, and conversion result parsing.
