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.
