ADS131B04QPWRQ1 General Description

The ADS131B04-Q1 is a four-channel, simultaneous-sampling, 24-bit, 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 battery-current measurements, to resistor-divider networks for high-voltage measurements, or to temperature sensors (such as thermistors or analog output temperature sensors).

The individual ADC channels can be independently configured depending on the sensor input. A low-noise, programmable gain amplifier (PGA) provides gains ranging from 1 to 128 to amplify low-level signals. The device features a global-chop mode to remove offset drift over temperature and time. Additionally, this device integrates offset and gain calibration registers to help remove signal-chain errors.

A low-drift, 1.2-V reference and precision oscillator are integrated into the device reducing printed circuit board (PCB) area. Optional cyclic redundancy checks (CRCs) on the data input, data output, and register map maintain communication integrity.

The complete analog front-end (AFE) is offered in a 20-pin TSSOP package and is specified over the automotive temperature range of –40°C to +125°C.
