PRELIMINARY

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 called 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). 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.

Detailed Description of Hardware

The MAX11131 is a 12-bit, 3Msps, 16-channel, ADC with SampleSet. Connect analog inputs to the AIN0..AIN15 header pins. (The first 6 analog inputs are also connected to the standard Arduino analog pins on the external connector.) The MAX6126 provides the 2.5V analog reference voltage. The MAX8511 provides a low-dropout 3.3V supply. The MAX14850 digital isolator translates the external logic signals in the range of 3.0V to 5.5V for use with the MAX11131’s 3.3V supply.

Using AIN14

Analog input pin CNVST/AIN14 is initially configured to support conversion-start command CNVST. To configure the board to use CNVST/AIN14 for analog input, cut jumper J16 and apply analog input at header H2.

Using AIN15

Analog input pin REF-/AIN15 is initially configured to support REF-. To configure the board to use REF-/AIN15 for analog input, cut jumper J15 and apply analog input at header H2.
