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.
FApplications
CD-ROM, DVD-ROM, MD, and optical discs
FFeatures
