4-channel BTL driver for CD player
and CD-ROM drives
BA5921FP
The BA5921FP is an IC with an internal 4-channel BTL driver for CD players and CD-ROM driver actuators and motors,
as well as an internal standard operational amplifier. In addition, the 28-pin HSOP package allows for application minia-
turization.
