4-channel BTL driver for CD players
BA5915FP
The BA5915FP contains a 4-channel BTL driver for CD player motors and actuators and a multi-purpose operational amplifier. Perfect for compact applications with the use of the HSOP 28-pin package.
FApplications CD players, CD-ROM
FFeatures 1) 4-channel BTL driver. 2) Wide dynamic range (3.55V (Typ.) when VCC = 5V and RL = 8Ω). 3) Internal thermal shutdown circuit. 4) Gain is adjustable with externally connected resistor.
5) Internal multi-purpose operational amplifier. 6) External mute pin enables the muting of the output current for channel 1. 7) Perfect for compact applications with the use of the HSOP 28-pin power package.
FAbsolute maximum ratings (Ta = 25 _C)
FRecommended operating conditions (Ta = 25 _C)
