The ADS131M04QPWRQ1 is a four-channel, simultaneous sampling, 24-bit, delta-sigma analog-to-digital converter (ADC) with wide dynamic range and low power consumption, making it ideal for use in automotive battery management systems (BMS). The ADC input can be connected directly to a shunt resistor for bidirectional battery current measurement, to a resistive divider network for high voltage measurement, or to a temperature sensor such as a thermistor or an analog output temperature sensor.

The ADS131M04QPWRQ1 can independently configure each ADC channel based on sensor input. A low-noise, programmable gain amplifier (PGA) provides gains from 1 to 128 to amplify low-level signals. In addition, the device integrates channel-to-channel phase calibration, offset and gain calibration registers to help eliminate signal chain errors.
