Mute detector IC for 3V sets
The BA3708F is a mute detector IC for 3V tape players. When the signal is higher than the input decision level VIN and longer than the song detect time, a pulse of width TW is output after the pulse delay time TD which begins when the input signal ends. The output is an open collector which enables direct drive of the plunger. A mute function is included which makes it possible to stop detection. FApplications 3V tape players FFeatures
1) Low supply voltage (can be operated at 1.8V; remended operating voltage is 2.0 to 5.0V). 2) Uses the song detection method to minimize incorrect detection caused by noise between songs. 3) The pulse delay...
