Analog Input Monaural Class-D Speaker Amplifier - BD27400GUL

BD27400GUL is a low voltage drive class-D monauralspeaker amplifier that was developed for cellular telephones,mobile audio products and the others.
The LC filter of the speaker output is unnecessary and theexternal part can compose a speaker amplifier at three.
Because the efficiency is high and is low consumption powerwith the class-D operation, it is the optimal for the applicationof the battery drive.
Also Current consumption of 0µA when standby and fasttransitions from standby to active with little pop noise make itis suitable for applications that switch repeatedly betweensuspended and active.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
