BD37068FV-M
内置2次后置滤波器/High-Voltage功能的汽车音响用声音处理器
内置6ch立体声输入选择器，调节信号电平并输出至ADC。分别内置6ch的用于降低从DAC输出的信号的带外噪声的2次后置滤波器与音量控制器，可将最大输出放大至5.2Vrms。还具有TDMA降噪功能，为整机设计的简化作出了贡献。

特点：
- 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.
