The ATR0808 is a laser diode driver for the operation of two different grounded laser diodes for DVD-RW/DVD+RW (650 nm) and CD-RW (780 nm).

It includes three channels for three different optical power levels which are controlled by a separate IC.

The read channel generates a continuous output level, whereas the channels 2 and 3 are provided as write channels with very fast switching speeds.

Current-controlled Output Current Source with 3 Input Channels Two Selectable Outputs for Grounded Laser Diodes Output Current per Write Channel: 350 mA Total Output Current: 500 mA 200 Ω Channel Input Resistance On-chip RF Oscillator Control of Two Different Swings by Use of Two External Resistors Oscillator Frequency Range from 200 MHz to 500 MHz Oscillator Swing: 1.
