The ADS131M06-Q1 is a six-channel, simultaneously sampling, 24-bit, delta-sigma
(ΔΣ), analog-to-digital converter (ADC) that offers wide dynamic range and low
power, making the device designed 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. Additionally, this device integrates channel-to-channel phase calibration
and offset and gain calibration registers to help remove signal-chain errors.
A low-drift, 1.2-V reference is
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 32-pin TQFP package and is specified over the automotive temperature
range of –40°C to +125°C.
