Product Details

describe:

The ADS130B04 -Q1 is a quad, simultaneous sampling, 16-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) that provides wide dynamic range, low power, and buffered analog inputs, making the device ideal for automotive batteries Management System (BMS). The ADC input can be connected directly to a shunt resistor for bidirectional battery current measurement, a resistor divider network for high voltage measurement, or a temperature sensor such as a thermistor or analog output temperature sensor.

Each ADC channel can be independently configured based on the BQ2014SN-D120 sensor input. A low-noise, programmable gain amplifier (PGA) provides gains of 1 to 128 to amplify low-level signals. The device features a global chopping mode that eliminates offset drift over temperature and time.

A low-drift, 1.2V reference and precision oscillator are integrated into the device, reducing printed circuit board (PCB) area. Optional Cyclic Redundancy Check (CRC) on data input, data output and register map maintains communication integrity.

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