DESCRIPTION The SP8024, SP8025, and SP8026 are high-speed, differential output APC amplifiers that integrate the photodiode and adjustable gain block on one chip. 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. FUNCTIONAL DIAGRAM
