特点:

  • AEC-Q100 Qualified
  • Built-in differential input selector that can select single-ended / differential input
  • Reduce switching pop noise of input gain control due to the built-in advanced switch circuit
  • Less out-of-band noise of DAC by built-in 2nd order post filter
  • Built-in buffered ground isolation amplifier to achieve high CMRR characteristics
  • Built-in TDMA noise reduction circuit reduces the additional components for external filter
  • Available to output 5.2VRMS by High-Voltage function (This device is possible to 3.2VRMS output by using another High-Voltage mode, VCCH=11.5V)
  • Available to control by 3.3V / 5V for I2C-bus controller
  • The input and output terminals are located together to arrange the flow of signal in a same direction making the PCB layout easier and PCB area smaller
