ADS131B02-Q1 2-Channel Delta-Sigma ADC Texas Instruments ADS131B02-Q1 2-Channel Delta-Sigma Analog-to-Digital Converter (ADC) is a two-channel, simultaneous-sampling, 24-bit, delta-sigma (ΔΣ) ADC. This ADC offers a 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 battery-current measurements, resistor-divider networks for high-voltage measurements, or temperature sensors (such as thermistors or analog output temperature sensors).
