Analog Devices Inc./Maxim Integrated MAX11156EVSYS#

Overview

MAX11156EVSYS# from Maxim Integrated is an evaluation system for the MAX11156 18-bit, 500ksps successive approximation register (SAR) analog-to-digital converter with ±5V true bipolar input range, integrated 4.096V reference and buffer, and 3mm × 3mm TDFN-12 package. It enables rapid validation of high-accuracy data acquisition in industrial control, medical instrumentation, and automatic test equipment.

For engineers reviewing the MAX11156EVSYS# datasheet, MAX11156EVSYS# pinout, MAX11156EVSYS# application, or MAX11156EVSYS# equivalent, this kit provides full hardware/software support for evaluating the MAX11156's 94.6dB SNR, ±2.8 LSB INL (typ), SPI-compatible interface, daisy-chain capability, and internal reference performance under real-world signal conditioning and timing constraints.

Technical Context

The MAX11156EVSYS# implements a complete signal chain around the MAX11156 ADC, including precision analog front-end conditioning, configurable reference routing (internal/external modes), isolated digital interface, and USB-based host communication via Maxim's GUI software. It supports all four reference modes (0–3) and validates the ADC's patented charge-pump architecture for direct sampling of high-impedance sources without external scaling resistors.

Designed for lab and benchtop use, the system delivers calibrated DC accuracy (±0.5 LSB DNL typ, ±2.8 LSB INL typ), AC performance verification (94.6dB SNR at 10kHz), and timing analysis (1.5µs conversion time, 500ns acquisition window), with provisions for external clock synchronization and multichannel daisy-chain expansion.

FAQ

What is the primary function of the MAX11156EVSYS#?

The MAX11156EVSYS# is a fully assembled and tested evaluation system for the MAX11156 18-bit SAR ADC. It provides hardware, firmware, and PC software to configure, acquire, and analyze analog signals using the MAX11156's full feature set-including internal reference, daisy-chain mode, and all four reference configurations-without custom PCB development.

Does the MAX11156EVSYS# support daisy-chaining multiple MAX11156 devices?

Yes, the MAX11156EVSYS# hardware and GUI software fully support daisy-chain operation of the MAX11156. The board implements proper signal termination and timing margins for multi-ADC serial cascading, enabling synchronized sampling across up to eight channels using a single SPI bus and CNVST line.

Can the MAX11156EVSYS# operate with an external reference instead of the internal 4.096V source?

Yes, the MAX11156EVSYS# supports all four reference modes defined for the MAX11156. It includes jumpers and layout provisions to route external references (2.5V–4.25V) to REFIO or REF pins, and the GUI allows real-time switching between internal bandgap, buffered internal, shared reference, and fully external configurations.

What software tools are included with the MAX11156EVSYS#?

The MAX11156EVSYS# ships with Maxim's Windows-based evaluation GUI, which provides real-time waveform display, FFT analysis, histogram plotting, noise measurement (LSBRMS), INL/DNL calculation, and export of raw binary or CSV data. Firmware updates and API documentation are available via Maxim's official support portal.

Is the MAX11156EVSYS# compatible with standard USB hosts and operating systems?

Yes, the MAX11156EVSYS# uses a standard CDC-class USB-to-serial bridge, requiring only native Windows drivers (included). It is compatible with Windows 10/11 (32/64-bit), and Linux/macOS users can access it via libusb-based terminal tools or custom Python scripts using the documented UART protocol.
