Overview

Audio ICs 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.

Key Features

1) Mute detection time and output pulse width can be set within a broad range by an external CR circuit. 2) Includes circuit for preventing errors due to song gap noise. 3) Includes over-current protection circuit. 4) Includes circuit for preventing errors when the power is turned on. 5) Detection can be stopped using an external input.
