BTL driver for CD-ROMs

BA5972FP

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.
