AD9662 3-Channel Laser Diode Driver

The AD9662 is a laser diode driver for high performance CD and DVD recordable drives. It includes three channels for three different optical power levels: the read channel generates a continuous output power level, whereas Channel 2 and Channel 3 are used as write channels having 0.8 ns rise/fall ti.

AD9662 Features

* Current-controlled current source with 3 input channels Output current for Channel 3

* 315 mA Output current for other channels

* 210 mA Rise time/fall time of 0.8 ns On-chip oscillator Single 5 V power supply (±10%) Low output overshoot Low power consumption APPLICATIONS CD-RW drives DV
