Analog Signal Input Class D Amplifier for Piezo Speaker
GENERAL DESCRIPTION
NJU8752
is a monaural analog signal input class D
amplifier for Piezo speaker. The
NJU8752
includes
Inversion operational amplifier input circuit, PWM
modulator, Output short protector and a low voltage
detector. Input part operates on 3.3V(TYP) as power
supply and Output part operates up to 13.75V(MAX).
Therefore, it drives Piezo speaker with Higher volume
and High efficiency.
By using equivalent capacitance of Piezo speaker,
the
NJU8752
is configured as a BTL amplifier capable
of operating Piezo speaker with the minimum external
components. A BTL configuration eliminates the need
for external AC coupling capacitors.
Class D achieves high output-efficiency, which leads
to low power operation for Piezo speaker, thus the
NJU8752
is ideally suited for battery powered
applications.
