BTL driver for CD-ROMs
BA5972FP
The BA5972FP is a 4-channel BTL driver developed for use with CD-ROMs. A multi-purpose operational amplifier is equipped in each channel to allow use in a variety of applications. Also, by applying independent power supplies for both the pre-stage and power-stage, with the power-stage power supply further split into two so one power supply handles two channels each, a highly efficient driver has been realized. FApplications CD-ROM, DVD-ROM, MD, and optical discs FFeatures 1) Wide dynamic range (VOUT = 4V [Typ.] when PreVCC = 8V, PowVCC = 5V, and RL = 8Ω). 2) Internal thermal shutdown circuit. FAbsolute maximum ratings (Ta = 25_C)
3) Internal mute functions. 4) Internal standby functions.
