IC for Compact Disc Players
BA5947FP
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
