NJU8754
PRELIMINARY
Analog Signal Input Monaural Class D Power Amplifier
GENERAL DESCRIPTION
The
NJU8754
is an analog signal input monaural
class D power amplifier. The
NJU8754
includes
Inversion operatinal amplifier input circuit, PWM
modulator, an output-short protector and a low voltage
detector. The
NJU8754
incorporates BTL amplifier,
which eliminate AC coupling capacitors, capable of
driving up to 0.6W at 3.6V supply voltage with simple
external LC low-pass filters.
The
NJU8754
features high power-efficiency by
class-D operation and very small package, and is suited
for cellular phone, PDA, etc.
