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.
