ROHM Semiconductor 

Optical disc ICs

4-channel BTL driver for CD players

BA6898S / BA6898FP

The BA6898S / BA6898FP ICs contain a 4-channel BTL driver , 5V regulator (which requires an externally connected

PNP transistor), multi-purpose operational amplifier, and reset output for use with CD players. Also equipped with an

input pin for gain adjustment for all channels of the driver block so that the gain can be adjusted to the desired value

for your application. Furthermore, a built-in level shift circuit exists to further reduce the amount of external components

required.

FApplications

CD players, CD-ROM, and other optical disc equipment
