Features
  • Built-in differential input selector that can select single-ended / differential input
  • Reduce the shock noise when switching gain due to built-in advanced switch circuit
  • Decrease the out of band noise of DAC by built-in 2nd order post filter.
  • Built-in buffered ground isolation amplifier to realize high CMRR characteristics
  • No need to countermeasure using external components built-in TDMA noise reduction circuit
  • Package is SSOP-B40. Putting same direction input-terminals and output-terminals make PCB layout easier and PCB area smaller.
  • It is possible to control by 3.3V for I2C-BUS controller
  • AEC-Q100 Qualified.
