GENERAL DESCRIPTION

The SP8027 represents the next generation in Automatic Power Control (APC) amplifiers designed specifically for demanding pick-up head applications. Whereas typical APC products exhibit degradation of bandwidth and slower settling times at higher gain levels, the SP8027 features constant bandwidth (150MHz) and fast settling times (5ns) across the entire gain adjust range.

FEATURES

• Dual wavelength 650 and 780nm

• 150 MHz Bandwidth over all gains

• 400 V/µs Slew Rate

• 5 ns Setting Time

• 10 mV Differential Output Offset Voltage

• Potentiometer, Voltage or DAC programmable gain

• ± 6 dB External Gain Adjust

• Small 8-pin OPLGA package

APPLICATION

• CD-R, and CD-RW

• DVD+/-R, DVD+/-RW, and DVD-RAM
