Analog Devices Inc./Maxim Integrated MAX11615EVSYS+

Overview

MAX11615EVSYS+ from Maxim Integrated is an evaluation system comprising a USB-connected I2C master board and a fully assembled daughter board configured to evaluate the MAX11615EEE+, a 12-bit, 3V-supply, 8-channel SAR ADC with 2.048V internal reference and 1.7MHz I2C interface. It supports time-domain/frequency-domain/histogram analysis and DC parameter calculation (RMS, min/max, average) for analog signal characterization in lab and design validation environments.

For engineers reviewing the MAX11615EVSYS+ datasheet, MAX11615EVSYS+ pinout, MAX11615EVSYS+ application, or MAX11615EVSYS+ equivalent, this system enables rapid functional verification, ADC performance benchmarking (e.g., SNR, THD), I2C timing validation, and reference voltage stability assessment - all via Windows-compatible GUI software with up to 1M-sample capture depth.

Technical Context

The MAX11615EVSYS+ implements a two-board architecture: the MAX116XX I2C Master Board (USB-powered, FPGA-controlled, with LDOs generating +3.6V, +2.5V, +5V, and +1.2V rails) interfaces directly with a PC via USB and issues I2C commands to the daughter board. The MAX11615 evaluation kit daughter board hosts the MAX11615EEE+ in 16-pin QSOP, an on-board MAX6126AASA25+ 2.5V reference, test points for all 8 analog inputs (AIN0–AIN7), and configurable jumpers for power source, reference selection, and I2C routing.

Hardware operation requires external +5.5V/0.5A supply for the master board and supports optional external AVDD_EXT (3V) and REF (2.048V) inputs on the daughter board. Software features include real-time FFT, histogram sigma analysis (Mean ± 3σ/6σ), auto DC removal, and scan-mode configuration (single, sequential, differential) aligned with MAX11615 register mapping.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a semiconductor company specializing in precision analog, mixed-signal, and high-reliability ICs for industrial, medical, and communications applications.

The MAX11600–MAX11617 family targets low-power, high-speed I2C ADC applications in space-constrained systems where integrated reference, flexible channel count (4/8/12), and rail-to-rail input simplify sensor front-end design.

FAQ

What is the MAX11615EVSYS+ used for?

The MAX11615EVSYS+ is a complete evaluation system designed to characterize and validate the MAX11615EEE+ 12-bit, 8-channel, 3V I2C ADC. It enables engineers to perform real-time signal analysis-including time-domain waveform capture, FFT-based frequency-domain inspection, histogram distribution profiling, and DC parameter calculation (RMS, min/max, average)-using Windows-based GUI software without custom firmware development. The MAX11615EVSYS+ itself is not a production component but a lab tool for ADC evaluation.

Does the MAX11615EVSYS+ include the MAX11615EEE+ ADC?

Yes, the MAX11615EVSYS+ includes a fully assembled and tested daughter board with the MAX11615EEE+ pre-soldered in 16-pin QSOP package. The daughter board also integrates the MAX6126AASA25+ 2.5V voltage reference, test points for all 8 analog inputs (AIN0–AIN7), and configurable jumpers for power, reference, and I2C routing - enabling immediate evaluation of the MAX11615EEE+ out-of-the-box.

What software and drivers are required for the MAX11615EVSYS+?

The MAX11615EVSYS+ requires the official MAX11600–MAX11617 EV system software: INSTALL.EXE (installer), MAX11600-11617.EXE (main GUI application), FTD2XX.INF (USB-to-UART driver), and USB_Driver_Help.PDF (installation guide). It supports Windows 2000, XP, and Vista (32-bit only). Driver installation requires administrator privileges and accepts unsigned driver warnings - no additional SDK or third-party tools are needed to operate the MAX11615EVSYS+.

Can the MAX11615EVSYS+ evaluate other ADCs in the MAX116xx family?

Yes - the MAX11615EVSYS+ daughter board is pin-compatible with other members of the MAX11600–MAX11617 family. While it ships with the MAX11615EEE+, it can evaluate the MAX11609EEE+ (10-bit, 3V, 8-channel) and MAX11603EEE+ (8-bit, 3V, 8-channel) using the same hardware; users simply select the target device in the software's "Select the ADC device" dropdown. Free samples of alternate variants are available from Maxim upon request.

What power supplies are needed to operate the MAX11615EVSYS+?

The MAX11615EVSYS+ requires one +5.5V/0.5A DC power supply connected to the DVDD and DGND banana jacks on the master board. The daughter board is powered by default from the master board (JU4 shunt position 1-2); alternatively, a clean 3V supply can be applied to the AVDD_EXT test point (JU4 1-3). No additional power sources are required for basic operation - all onboard LDOs (3.6V, 2.5V, 5V, 1.2V) are internally regulated from the +5.5V input.
