NJU8761 Datasheet (JRC) - Analog Signal Input Monaural Class-D Power Amplifier

NJU8761, Analog Signal Input Monaural Class-D Power Amplifier

The NJU8761 is an analog signal input monaural class-D amplifier for Piezo speaker.

The NJU8761 incorporates BTL amplifiers, which eliminate AC coupling capacitor.

The input block operates on 2.6V(Min.) as power supply and the output block operates up to 12V, therefore it can output close to 17.5VP-
