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.

FAbsolute maximum ratings (Ta = 25_C)
