Product Details

Analog-to-digital converters (ADCs) provide accurate measurement and conversion of signals to digital format for sensing in many electronic applications such as industrial, medical and sensor systems. The MAX11131 is a high-speed, 16 channel, 12-bit ADC with a unique feature, SampleSet. SampleSet allows users to tailor individual sample rates for each input channel. Development with ADCs involves expertise in analog systems, power supplies, digital interfaces and firmware. Now, enter the MAX11131BOB to accelerate the development process.

The MAX11131BOB Breakout Board provides for rapid prototyping and development with the MAX11131 (a 12-bit, 3Msps, 16-channel, ADC with SampleSet). The MAX11131BOB interfaces to any Arduino™-compatible or mbed.org™ compatible platform system with expansion ports configurable for SPI communication. Additionally, the MAX11131BOB works with systems that have a Pmod™ connection, a 2x6 right-angle header at board edge (compatible with Digilentinc.com Pmod™ interface spec) Interface type 2A (expanded SPI) on 2x6 header at board edge. MAX11131 also comes with schematics, design files, and firmware for immediate use and forking to future projects.

The board interfaces to SPI with logic levels in the range 3.0V to 5.5V.

The board comes installed with MAX11131ATI+ installed. Example firmware is provided for Arduino and mbed. org system boards.
