DESCRIPTION
The SP8126B 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
780mn 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 DVDRW, DVDRAM and CDRW
systems. The wide 2V output swing also allows better system performance, through improved
dynamic range.
