BD5431EFS_11 Datasheet, PDF (1/5 Pages) Rohm – Silicon monolithic integrated circuits

1/4
STRUCTURE:
Silicon monolithic integrated circuits
PRODUCT:
Stereo Class-D Power Amplifier For Speaker
TYPE:
BD5431EFS
PACKAGE:
HTSSOP-A44
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℃)
