4-channel BTL driver for CD players
and CD-ROMs
BA5970FP
The BA5970FP is a 4-channel BTL driver developed to drive CD player motors and actuators. The driver input stage
contains an operational amplifier, supports a variety of input formats, and allows simple configuration of a filter.
FApplications
CD players, CD-ROM
