ADS131B23PHPR

Analog To Digital Converters (ADC) Overview

The ADS131B23 is a high-voltage battery-pack monitor featuring two simultaneous-sampling 24-bit ADCs for current-shunt measurements and one multiplexed 16-bit ADC for voltage and temperature sensing. It operates with an APWR supply range of 4V to 16V and digital supplies from 2.9V to 5.5V. The device supports data rates from 500SPS to 64kSPS, includes programmable full-scale ranges (±39mV to ±312.5mV for current), and integrates internal linear regulators. It provides diagnostic features, overcurrent comparators, and nine GPIOs with PWM capability in a 48-pin HTQFP package.
