Analog Signal Input Class D Amplifier
with DC-DC Converter for Piezo Speaker
GENERAL DESCRIPTION
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 and high efficiency.
The
NJU8753
incorporates BTL amplifier, which
eliminate AC coupling capacitors, capable of driving
monaural Piezo speaker with simple external LC
low-pass filters.
Class D operation achieves lower power operation for
Piezo speaker, thus the NJU8753 is suited for battery-
powered applications.
