Optical disc ICs
4-channel BTL driver for CD players
BA6198S / BA6198FP
The BA6198S and BA6198FP are ICs with an internal 4-channel BTL power driver for CD players, a 5V regulator (re-
quires attached PNP transistor), standard operational amplifier, and reset output pin. All driver channels have a gain
adjustment pin, and so can be set to the desired gain. In addition, 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 (BA6198FP), allowing for application miniatur-
ization.
2) Gain is adjustable with an attached resistor.
3) Internal thermal shutdown circuit.
4) Internal 5V regulator (requires attached PNP resis-
tor)
5) Internal standard operational amplifier.
6) Reset output pin.
