The MAX11129–MAX11132 are 12-/10-bit with external reference and industry-leading 1.5MHz, full linear bandwidth, high speed, low-power, serial output successive approximation register (SAR) analog-to-digital converters (ADCs). The MAX11129–MAX11132 include both internal and external clock modes. These devices feature scan mode in both internal and external clock modes. The internal clock mode features internal averaging to increase SNR. The external clock mode features the SampleSet™ technology, a user-programmable analog input channel sequencer. The SampleSet approach provides greater sequencing flexibility for multichannel applications while alleviating significant microcontroller or DSP (controlling unit) communication overhead.
The internal clock mode features an integrated FIFO allowing data to be sampled at high speeds and then held for readout at any time or at a lower clock rate. Internal averaging is also supported in this mode improving SNR for noisy input signals. The devices feature analog input channels that can be configured to be single-ended inputs, fully differential pairs, or pseudo-differential inputs with respect to one common input. The MAX11129–MAX11132 operate from a 2.35V to 3.6V supply and consume only 15.2mW at 3Msps.
The MAX11129–MAX11132 include AutoShutdown™, fast wake-up, and a high-speed 3-wire serial interface. The devices feature full power-down mode for optimal power management.
The 48MHz, 3-wire serial interface directly connects to SPI, QSPI™, and MICROWIRE® devices without external logic.
Excellent dynamic performance, low voltage, low power, ease of use, and small package size make these converters ideal for portable battery-powered data-acquisition applications, and for other applications that demand low power consumption and small space.
The MAX11129–MAX11132 are available in 28-pin, 5mm x 5mm, TQFN packages and the MAX11131 is available in a 28-pin TSSOP package. All devices operate over the -40°C to +125°C temperature range.

Product Detail

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.
