Description

The BA5947FP is a 4-channel BTL driver

developed for compact disc players.

3 out of 4 channels are PWM input

direct connection type and incorporate

primary filter.

Features

1) 4-channel BTL driver

2) Set space saving by adoption of HSOP28

3) Built-in OP amp.

4) Wide dynamic range

5) Built-in thermal shutdown circuit

6) High efficient supply voltage setting due to independent supply

(Pre Vcc, Pow Vcc of CH1, CH2 and Pow Vcc of CH3, CH4)

7) For CH4, input pin can be switched by SW pin

Applications

Compact disc players, Other optical disc appliances
