Small-sized Class-D Speaker Amplifiers

Filter-Less Class-D

Monaural Speaker Amplifier

BD27400GUL

General Description

Key Specifications

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.

Operating Temperature Range:

Package(s)

W(Typ) x D(Typ) x H(Max)

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.
