GENERAL DESCRIPTION

The SP8130 is a high-speed, differential output APC amplifier that integrates the photodiode and

adjustable gain block on one chip. Independent gain control allows individual adjustment for 780nm

and 650nm wavelength operation, as found in CD/DVD optical storage drives. This allows the user to

control the laser power of the system in high-speed DVD+/-RW, DVD-RAM and CD-RW systems.

The wide 2V output swing also allows better system performance, through improved dynamic range.
