NJU8755

PRELIMINARY

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.
