BD37069FV-M
Sound Processor for Car Audio with Built-in High-Voltage Amplifier and 2nd Order Post Filter

BD37069FV-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.
