The ADS131B02QPWRQ1 is a two-channel simultaneous sampling 24-bit delta-sigma (ΔΣ) ADC. The ADC's wide dynamic range, low power consumption, and buffered analog input make 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), a resistive divider network (for high voltage measurement), or a temperature sensor such as a thermistor or an analog output temperature sensor.
