GENERAL DESCRIPTION
The SP8036 represents the next generation in Automatic Power Control (APC) amplifiers designed specifically for demanding pick-up head applications. With its integrated photo detector, the SP8036 monitors light intensity of the laser diode in CD-R, CD-RW, DVD+/-R, DVD+/-RW, and DVD-RAM assemblies and converts this light to an output voltage. The magnitude of this voltage signal corresponds to the laser power intensity and is subsequently fed back to the laser diode driver to control the laser output power.
