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.

FApplications

CD players, CD-ROM drives

FFeatures

1) 4-channel BTL driver.

2) HSOP 28-pin power package allows for application

miniaturization.

3) Wide dynamic range. (typically 3.6V when VCC = 5V

and RL = 8Ω)

4) Internal thermal shutdown circuit.

5) Gain is adjustable with an attached resistor.

6) Internal standard operational amplifier.

7) Output current is mutable with an external mute pin.

FAbsolute maximum ratings (Ta = 25_C)

FRecommended operating conditions (Ta = 25_C)
