●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

●Line up matrix
