Small-sized Class-D Speaker Amplifiers
Filter-Less Class-D
Monaural Speaker Amplifier
BD27400GUL
General Description
BD27400GUL is a low voltage drive class-D monaural
speaker amplifier that was developed for cellular
telephones, mobile audio products and the others.
The LC filter of the speaker output is unnecessary and
the external part can compose a speaker amplifier at
three.
Because the efficiency is high and is low consumption
power with the class-D operation, it is the optimal for the
application of the battery drive.
Also Current consumption of 0μA when standby and fast
transitions from standby to active with little pop noise
make it is suitable for applications that switch repeatedly
between suspended and active.
