描述

The MAX11190 is a 4-channel, dual, multiplexed, 12-bit, compact, high-speed, low-power, successive approximation analog-to-digital converter (ADC). This high-performance dual ADC includes high-dynamic range sample-and-holds and a high-speed serial interface. This ADC accepts a full-scale input from 0V to the reference voltage.

The device features two dual, single-ended analog inputs connected to two ADC cores using 2:1 MUXs. The device also includes a separate supply input for data interface and dedicated inputs for reference voltage.

This device operates from a 2.2V to 3.6V supply and consumes only 10.5mW at 3Msps. The device includes full power-down mode and fast wake-up for optimal power management and a high-speed 3-wire serial interface. The 3-wire serial interface directly connects to SPI, QSPI, and MICROWIRE® devices without external logic. Each of the two internal ADCs has its own dedicated DOUTA/DOUTB for faster data communication.

Excellent dynamic performance, low voltage, low power, ease of use, and small package size make this converter ideal for simultaneous data-acquisition applications, and for other applications that demand low power consumption and minimal space.

The device is available in a 3mm x 3mm, 16-pin TQFN package and operates over the -40°C to +125°C temperature range.
