ATR0809 is a laser diode driver for the operation of two different grounded laser diodes for DVD-RW/+RW (650 nm) and CD-RW (780 nm).

It includes four channels for four different optical power levels.

All channels (channel 1 = read channel, channel 2, 3, 4 = write channels) can be controlled by fast switches.

Current-controlled Output Current Source with 4 Input Channels Two Selectable Outputs for Grounded Laser Diodes Up to 350 mA Output Current per Channel Total Output Current up to 500 mA On-chip RF Oscillator Oscillator Frequency Range from 200 MHz to 500 MHz Individual Setting of RF Oscillator Current on Each Output by External Resistors Maximum Oscillator Current Amplitude 100.
