4-channel BTL driver for CD players

BA6197FP

The BA6197FP, an IC for CD players, has a 4-channel BTL driver, 5V regulator (attached PNP transistor required), stan-

dard operational amplifier, and internal reset output linked to an internal thermal shutdown circuit. The driver has gain

adjustment input pins for each channel, allowing gain to be set to the desired value. Also, the internal level shift circuit

helps reduce the number of attached components.

FApplications

CD players, CD-ROM drives and other optical disc de-

vices

FFeatures

1) 4-channel BTL driver on a HSOP 28-pin power pack-

age, allowing for application miniaturization.

2) Gain is adjustable with an attached resistor.

3) Internal thermal shutdown circuit with hysteresis ca-

pabilities.

4) Internal 5V regulator. (required attached PNP tran-

sistor)

5) Internal standard operational amplifier.

6) Reset output pin.
