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.
