STRUCTURE:

PRODUCT:

Silicon monolithic integrated circuits

Stereo Class-D Power Amplifier For Speaker

TYPE:

BD5431EFS

HTSSOP-A44

PACKAGE:

FEATURES:

1) Differential Analog / PWM inputs

2) High efficiency and low heat generation eliminates external heat-sinks

3) Eliminates pop noise generated when the power supply goes on/off, or when the power supply is

suddenly shut off

4) High quality muting performance is realized by using the soft-switching technology

5) Incorporates a master/slave function that enables synchronous operation when several

units are used simultaneously

6) Allows the internal PWM sampling clock frequency to be adjusted

○Absolute maximum ratings (Ta=25℃)
