5-channel BTL driver for CD players
BA6796FP
The BA6796FP, an IC designed for CD and MD players, has a 5-channel BTL power driver and a standard operational amplifier. The spindle and tray driver share a single output buffer, and are specified with a control pin. In addition, the internal level shift circuit reduces the number of attached components. FApplications CD players, CD-ROM drives, MD players and other optical disc devices FFeatures 1) 5-channel BTL driver in a 28-pin HSOP package, allowing for application miniaturization. 2) The five drivers are turned on and off according to control pin logic combinations. 3) The tray driver operates even when the servo power supply drops. FAbsolute maximum ratings (Ta = 25_C)
4) Internal thermal shutdown circuit. 5) Gain is adjustable with an attached resistor. 6) Internal standard operational amplifier.
FRecommended operating conditions (Ta = 25_C)
