Mute detector IC
BA336 / BA338 / BA338L
The BA336, BA338 and BA338L are monolithic ICs designed for mute detection and tape end detection.
When a duration of silence (52dBm or less) exceeds the time constant set with an external CR circuit, a song gap is identified, and after this a plunger control signal is output during a pulse whose width is determined by another external CR circuit.
These functions are contained in a compact 9-pin package.
The circuit configuration consists of a pre-amp with limiter, a comparator flip-flop, and a driver.
Circuitry is also included which prevents errors when the power is turned on, and measures have been taken to prevent errors due to excessive...
