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 DVD-RW, DVD+RW, MO drives Laser diode current switching GENERAL DESCRIPTION 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 times.
All channel currents are sum...
