Note 1) All voltage values are specified as VSS=VSSO=0V.
Note 2) If the LSI is used on condition beyond the absolute maximum rating, the LSI may be destroyed. Using LSI within electrical characteristics is strongly recommended for normal operation. Use beyond the electrical characteristics conditions will cause malfunction and poor reliability.
Note 3) Decoupling capacitors should be connected between VDD-VSS and VDDO-VSSO due to the stabilized operation.




Description

The NJU8713 is a Switching Driver for a class D Amplifier including Separated Power Source terminals between Input and Output, BEEP and BPZ (Bipolar Zero) output circuits. It converts 1bit digital signal input, such as PWM or PDM signal, to an analog signal output through a simple external LC low-pass filter.

The NJU8713 realizes very high power-efficiency because of the class D operation. Therefore, it is suitable for portable audio set and others.
