Optical disc ICs
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.
Applications
CD players, CD-ROM drives and other optical disc de-
vices
Features
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.
