Dual 20 Watt BTL audio amplifier

General Description:

The AN7198Z is an audio power IC developed for the sound output of car audio (Dual 20 W).A capacitor and a resistor between the output pin and GND to stop oscillation are built-in so that a space saving of set is possible. Also, it is incorporates an industry's first superior muting circuit which is free from shock noise, so that a shock noise design under the set transient condition can be made easily when the muting circuit is used together with its standby function.
