The BA5972FP is a 4-channel BTL driver developed for use with CD-ROMs. A multi-purpose operational amplifier is equipped in each channel to allow use in a variety of applications. Also, by applying independent power supplies for both the pre-stage and power-stage, with the power-stage power supply further split into two so one power supply handles two channels each, a highly efficient driver has been realized.

● Features

1) Wide dynamic range (VOUT = 4V [Typ.] when PreVCC

= 8V, PowVCC = 5V, and RL = 8Ω).

2) Internal thermal shutdown circuit.

3) Internal mute functions.

4) Internal standby functions.

● Applications

CD-ROM, DVD-ROM, MD, and optical discs
