Automobile Chips ADS131B04QPWRQ1 24 Bit Analog to Digital Converter 20-TSSOP Package

Product Description Of ADS131B04QPWRQ1

The ADS131B04QPWRQ1 is a four-channel, simultaneoussampling, 24bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) that offers wide dynamic range, low power, and buffered analog inputs, making the device an excellent fit for automotive battery management systems (BMS). The ADC inputs can be directly interfaced to shunt resistors for bidirectional batterycurrent measurements, to resistor-divider networks for high-voltage measurements, or to temperature sensors (such as thermistors or analog output temperature sensors).
