Audio ICs Mute detector IC BA3703F The BA3703F is a mute detector designed for car stereos. It features low external parts count, and can detect mute whether the tape is playing or being fast-forwarded. It features a wide power supply voltage range (6.0V to 16.0V) and is ideal for use in car stereos and other audio equipment. Application Car stereos Features 1) Can detect mute during playback and fast-forward. 2) The signal detect and mute detect times can be set using attached components. 3) Wide operating voltage range (6.0V to 16.0V).
