NJU8758V

Analog Signal Input Monaural 1.5W Filterless Class D Power Amplifier

Japan Radio Corporation  

NJU3857558

FUNCTIONAL DESCRIPTION

(1) Signal Output (OUTP, OUTN)

The OUTP and OUTN generate PMW output signal.

(2) Standby (STBYb)

By setting the STBYb and MUTEb terminal to “L”, the standby mode is enabled. In the standby mode, the

entire functions of the NJU8758 enter a low-power state, and the output terminals(OUTP and OUTN) are in

high impedance.

(3) Mute (MUTEb)

By setting the MUTEb terminal to “L”, the Mute function is enabled, and the output terminals(OUTP and

OUTN) output square wave(Duty: 50%).

The NJU8758 has a built-in circuit for the pop-noise reduction at power-on. However the control with the

sequence can realize more effective the pop-noise reduction.
