BA6196FP

Optical disc ICs 4-channel BTL driver for CD players BA6196FP The BA6196FP is an IC designed CD players and has an internal 4-channel BTL driver, 5V regulator (attached PNP transistor required), standard operational amplifier and a thermal shutdown feature. The driver has gain adjustment input pins for each channel, allowing gain to be set to the desired value. Also, 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 in a 28-pin HSOP package, for miniaturization of applications. 2) Gain is adjustable with an attached resistor. 3) Internal thermal shutdown circuit. 4) Internal 5V regulator. (required attached PNP transistor) 5) Internal standard operational amplifier.
