Sound Processor for Car Audio with Built-in High-Voltage Amplifier and 2nd Order Post Filter - BD37069FV-MBD37069FV-M is a sound processor developed for car audio with built-in selector of six stereo inputs and output interfaced to ADC after adjusting signal level. BD37069FV-M has a 6-channel volume circuit and built-in 2nd order post filter which reduces the out-of-band noise. The High-Voltage function is capable to reach up to 5.2VRMS maximum output. Furthermore, the IC is simple to design due to the built-in TDMA noise reduction systems.

Features:
- 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
