AS8510 Analog Front-End

Data acquisition IC for battery management, dual ADC

 

The AS8510 Data Acquisition Front-End IC is a virtually offset free, low noise, 2 channel measurement device. It is tailored to accurately measure battery current from mA range up to kA range in combination with a 100 uOhm shunt resistor connected in series with the battery rail. Through the second measurement channel it enables capture of either battery voltage synchronous with the current or to measure the analog output of an internal or external temperature sensor.

Key Features

  • First 16 bit dual ADC + PGA data acquisition ASSP with zero offset  as a  flexible sensor interface
  • Offset  <1LSB
  • Noise <1 LSB@1kHz, 1 Sigma

Key Benefits

  • Highest accuracy dual ADC for signal conditioning up to 4 kHz
  • Flexible concept enables short time to market in evolving field of battery management
  • Full AEC Q 100 conformance
