The MAX22000 is an industrial-grade configurable analog input/output device that can be configured on-the-fly in software as a voltage input or output, or current input or output. Additional inputs are available to measure other analog signals.

The device offers an 18-bit DAC with fast settling time as well as a 24-bit delta-sigma ADC. The ADC and DAC can individually choose between an internal or an external reference.

The MAX22000 supports the ADC with a low-noise programmable gain amplifier (PGA), with high-voltage and low-voltage input ranges to support RTD and thermocouple measurements. Additional auxiliary inputs are provided to measure cold junction temperatures on-board.

The MAX22000 communicates through a high speed 20MHz SPI bus for all configuration and management information as well as for conversion results. An optional 8-bit CRC enhances the reliability of the SPI interface, protecting against all 8-bit bursts and double-bit errors.

The MAX22000 operates from 2.7V to 3.6V analog and digital supplies and up to ±24V high-voltage supplies. The device is available in a 64-pin LGA package and operates over the -40°C to +125°C industrial temperature range.
