NJU8753 Datasheet (JRC) - Analog Signal Input Class D Amplifier

NJU8753, Analog Signal Input Class D Amplifier

The NJU8753 is an analog signal input class D power amplifier with DC-DC converter for Piezo speaker.

Input part operates on 2.85V(typ) and a built-in DC-DC converter generates variable output voltage(up to 12V) with input voltage(2.6 to 4.2V).

Therefore, it drives Piezo speaker with louder sound an
