High Performance Class-D Speaker / Headphone Amplifier Series
2.5W Monaural Class-D Speaker
Amplifier for Differential Analog Input
BD5632NUX, BD5634NUX, BD5638NUX
No.10075ECT09
●Description
BD5632NUX, BD5634NUX and BD5638NUX are a low voltage drive class-D speaker amplifier that was developed for
mobile phones, mobile audio products and the others.
BD5632NUX has a fixed gain of 6dB, BD5634NUX has a fixed gain of 12dB, and BD5638NUX has a fixed gain of 18dB.
It is suitable for the application of battery drive because of high efficiency and low power consumption.
Also, stand-by current is 0µA (typ.), and fast transitions from standby to active with little pop noise. It is suitable for
applications that switch repeatedly between stand-by and active.
●Features
1) LC Filter less
2) Only 3 external components
3) High power 2.5W/4ohm/BTL （VDD=5V, RL=4ohm, THD+N=10%, typ.）
4) High power 0.85W/8ohm/BTL （VDD=3.6V, RL=8ohm, THD+N=10%, typ.）
5) Analog differential input / PWM digital output
6) Pop noise suppression circuit
7) Standby function (Mute function)
8) Protection circuit
(Short protection [Auto recover without power cycling], Thermal shutdown, Under voltage lockout)
9) Ultra small package VSON008X2030 (2.0×3.0×0.6mmMAX)
●Applications
Mobile phones, PND(Personal Navigation Device), DSC, PDA, etc
