Sound Processor for car audio built-in High-Voltage function and 2nd order post filter - BD37068FV-MIt is built-in input selector of 6 stereo source and output to ADC after adjusting signal level. And built-in 2nd order post filter to reduce out of band noise and 6ch Volume circuit. It is possible to out until 5.2Vrms at maximum output. (High Voltage function) Moreover, it is simple to design set by built-in TDMA noise reduction systems.
