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.
