BD37068FV-M
內建2次後置濾波器/High-Voltage功能的汽車音響用聲音處理器

內建6ch立體聲輸入選擇器,調節訊號電平並輸出至ADC。分別內建6ch的用於降低從DAC輸出的訊號的內建外雜訊的2次後置濾波器與音量控制器,可將最大輸出放大至5.2Vrms。還具有TDMA降噪功能,為整機設計的簡化作出了貢獻。

功能:

  • 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
  • It is possible to output 5.2Vrms by High-Voltage function
  • 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.
