Analog Signal Input Stereo Class D Power Amplifier
!
GENERAL DESCRIPTION
The
NJU8755
is an analog signal input stereo class D
power amplifier. The
NJU8755
includes Inversion
operational amplifier input circuit, PWM modulators, an
output-short protector and a low voltage detector. The
NJU8755
incorporates BTL amplifiers, which eliminate
AC coupling capacitors, capable of driving up to
1.2W/channel with simple external LC low-pass filters.
Class-D operation achieves high power-efficiency,
which achieves longer battery life for battery powered
applications, thus the
NJU8755
is suited for portable
audio, note-PC, etc.
