ams AS8510 Data Acquisition Front-End IC

ams AS8510 Data Acquisition Front-End IC is a virtually offset free, low noise, two channel measurement device. AS8510 is tailored to accurately measure battery current from mA range up to kA range in conjunction with a 100μΩ shunt resistor in series with the battery rail. Through the second measurement channel it enables capture of, either battery voltage synchronous with the current measurement, or, measure the analog output of an internal or external temperature sensor. Both channels are matched and can either measure small signals up to ±160mV versus ground, through programmable gain amplifier or larger signals in the 0 to 1V range without the amplifier.

Key Features
  • 3.3V supply voltage
  • Two High resolution 16 bit Σ−Δ A/D converters
  • Programmable sampling to enable data throughputs from less than 1Hz to 8kHz
  • Zero Offset for both channels
  • Independent control of data rate on both channels
  • Precision, low noise, programmable gain amplifiers for both channels with gains 5, 25, 40, 100 to support wide dynamic ranges.
  • Option for multiplexing either one differential input, or two single ended inputs or the internal temperature sensor on one channel
  • Programmable current source for external temperature sensor connectable to any of the inputs
  • High precision and high stability 1.2V reference voltage source
  • Digital signal processing with filter options for both channels
  • Four operating modes providing
    • Continuous data acquisition (or)
    • Periodic single-shot acquisition, (or)
    • Continuous acquisition on threshold crossing of programmed current levels (or)
    • A combination of the above
  • On chip high-precision 4MHz RC oscillator or option for external clock
  • -40ºC to +125ºC ambient operation
  • AEC - Q100 automotive qualified
  • Internal chip ID for full traceability
  • SSOP-20 pin package
Applications
  • The AS8510 is ideal for shunt based batteries sensor. For high-side current sensing, the input signal may be conditioned using ams
  • device AS8525 before applying to this device.
