Product Details

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.

High output power 2.5W typ.(VDD=5V,RL=4Ω,THD+N=10%,BTL)
Very small package 9-Pin WL-CSP (1.5*1.5*0.55mmMAX)
Gain selectable by external resistor
LC Filter less
Stand by function
Protection circuitry (Short protection, Thermal shutdown, Under voltage lockout)
Analogue differential input / PWM digital output
Pop noise suppression circuitry
