Product Details

BD5634NUX 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 only 3 external components are needed by fixed gain 12dB. 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.

No LC filter required
Only 3 external components
High power 2.5W / 4Ω / BTL (VDD=5V, RL=4Ω, THD+N=10%)
High power 0.85W / 8Ω / BTL (VDD=3.6V, RL=8Ω, THD+N=10%)
Gain 12dB
analogue differential input / PWM digital output
Pop noise suppression circuit
Built-in standby function
Protection circuit (Short protection [Auto recover without power cycling], Thermal shutdown, Under voltage lockout)
