Analog Devices Inc./Maxim Integrated MAX11613EVSYS+

Overview

MAX11613EVSYS+ from Maxim Integrated is an evaluation system comprising a USB-connected I2C master board and a fully assembled daughter board designed to evaluate the MAX11613EUA+, a 12-bit, 4-channel, 3V-supply analog-to-digital converter with 2.048V internal reference. It supports up to 1 MSPS data capture, real-time time/frequency/histogram analysis, and DC parameter calculation (RMS, min/max, average) for precision sensor and industrial signal acquisition.

For engineers reviewing the MAX11613EVSYS+ datasheet, MAX11613EVSYS+ pinout, MAX11613EVSYS+ application, or MAX11613EVSYS+ equivalent, this system provides immediate hardware-software validation of MAX11613EUA+ performance-including I2C interface timing, reference stability, channel scanning behavior, and noise floor-without custom PCB design or firmware development.

Technical Context

The MAX11613EVSYS+ integrates a Spartan-3A FPGA-based master controller (Xilinx XC3S50A), a MAXQ2000-RAX+ microcontroller, and on-board LDOs (MAX1793EUE50+, MAX1983EUT+) to generate stable 3.6V, 2.5V, and 1.2V rails. It routes I2C commands from PC software via USB-to-UART bridge to the daughter board's MAX11613EUA+ ADC over a 20-pin header interface.

Hardware features include banana jacks for DVDD/DGND power input, multipurpose test points (AIN0–AIN3, REF, SCL, SDA, 3.6V), configurable jumpers for reference selection (internal/external), supply sourcing (master/external), and I2C routing (onboard/user-supplied), plus shunt-based configuration for all critical operating modes.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power management ICs for industrial, medical, and communications applications.

The MAX11600–MAX11617 product line delivers low-power, high-speed I2C ADCs targeting space-constrained, battery-operated, or thermally sensitive systems requiring integrated reference and minimal external components.

FAQ

What does the MAX11613EVSYS+ evaluate?

The MAX11613EVSYS+ evaluates the MAX11613EUA+ - a 12-bit, 4-channel, 3V-supply ADC with 2.048V internal reference. The system includes a master board (USB interface, FPGA, microcontroller, LDOs) and a daughter board (MAX11613EUA+, voltage reference, test points, jumpers). It does not evaluate other MAX116xx variants unless physically substituted with their respective daughter boards.

Does the MAX11613EVSYS+ require an external power supply?

Yes - the MAX11613EVSYS+ requires a +5.5V, 0.5A external power supply connected to the DVDD and DGND banana jacks on the master board. The daughter board receives regulated 3.6V and 2.5V from the master board by default, but can be powered externally via the AVDD_EXT connector using jumper JU4.

Can the MAX11613EVSYS+ be used with non-Windows operating systems?

No - the official MAX11613EVSYS+ software (MAX11600-11617.EXE) and USB drivers are validated only for Windows 2000, XP, and Vista (32-bit). No Linux or macOS drivers or GUI applications are provided by Maxim for the MAX11613EVSYS+.

What software features are supported by the MAX11613EVSYS+ GUI?

The MAX11613EVSYS+ GUI supports real-time time-domain plotting with DC removal and auto-scaling, frequency-domain FFT analysis, histogram generation with (Mean ± 3σ) or user-defined range, and single-conversion display showing ADC codes and calculated voltages per channel. It also computes RMS, min/max, average DC, and frequency metrics automatically.

How is the reference voltage configured on the MAX11613EVSYS+ daughter board?

Reference configuration on the MAX11613EVSYS+ daughter board is controlled by jumper JU3: position 1-2 connects AIN3/REF to the AIN3 test point (default); 1-3 connects the on-board MAX6126AASA25+ 2.5V reference to the AIN3/REF pin; 1-4 routes an external reference to the REF test point. The software's Ref Voltage setting must match the physical jumper state for accurate voltage calculations.
