MAX132EWG+

Analog To Digital Converters (ADC) Overview

The MAX132EWG+ is a CMOS, 18-bit plus sign, serial-output analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It utilizes multi-slope integration to achieve high-resolution conversions at rates up to 100 conversions per second. The device features a low conversion noise of 15µVRMS and supports a ±512mV full-scale input range with 2µV/LSB resolution. Typical supply current is 60µA in normal operation and reduces to 1µA in sleep mode. It includes four user-programmable digital outputs for external control and operates within an extended temperature range of -40°C to +85°C.
