AS89010

Features

  • 4-channel Current-to-Digital Converter (ADC) with I²C Control / Output
  • 16-bit (internal 20 bit) digital serial output
  • Dynamic range 1: 1.000.000 (in combination with AS73210)
  • 16-bit/400kHz fast I²C interface with programmable slave addresses
  • Automatic power down (sleep function)
  • Scaling the internal 20-bit per shifter on 16-bit output
  • Temperature compensation on chip

Benefits

  • Conversion of 4 sensor signals of photodiodes or other sensors with current signal output
  • High linearity of amplifying, no cross talking
  • High absolute accuracy without additional sources
  • High reliability internal reference source generation
  • Low power consumption
