Monaural Class-D Speaker Amplifier

BD5461GUL

No.10101EAT02

●Description

BD5461GUL is a low voltage drive class-D monaural speaker amplifier that was developed for cellular phones, mobile

audio products and the others.LC-filter of speaker output is unnecessary, and the number of external components is three.

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) No LC filter required

2) Only three external components

3) High power 2.5W/4Ω/BTL (VDD=5V, RL=4Ω, THD+N=10%, typ.)

4) High power 0.85W/8Ω/BTL (VDD=3.6V, RL=8Ω, THD+N=10%, typ.)

5) Gain 12dB

6) Analog differential input / PWM digital output

7) Pop noise suppression circuitry

8) Built-in standby function

9) Protection circuitry (Short protection [Auto recover without power cycling], Thermal shutdown, Under voltage lockout)

10) Very small package 9-Bump WL-CSP (1.6*1.6*0.55mmMAX)

●Applications

Mobile phones, PDA, Mobile electronics applications, Note-book PC etc.
