BA5913FP-Y

Optical disc ICs 4-channel BTL driver for CD players and CD-ROM drives BA5913FP-Y The BA5913FP-Y 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 25-pin HSOP package allows for application miniaturization. FApplications CD players, CD-ROM drives FFeatures 1) 4-channel BTL driver. 2) Wide dynamic range (typically 3.6V when VCC = 5V and RL = 8Ω). 3) Internal thermal shutdown circuit. 4) Gain is adjustable with attached resistor. 5) Internal standard operational amplifier. 6) Can enter power save mode with standby pin. 7) HSOP 25-pin power package allows for application miniaturization.
