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).
