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 (requires 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 devices
FFeatures 1) 4-channel BTL driver on a HSOP 28-pin power package (BA6198FP), allowing for application miniaturization. 2) Gain is adjustable with an attached resistor.
3) Internal thermal shutdown circuit. 4) Internal 5V regulator (requires attached PNP resistor) 5) Internal standard operational amplifier. 6) Reset output pin.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
