The ATR0841 is a laser diode driver designed to operate two differently grounded laser diodes for DVD-RW/+RW (650 nm) and CD-RW (780 nm).

The device includes four channels for four different optical power levels.

The write channels (channel 2 to 4) can be controlled by fast LVDS (Low Voltage Differential Signaling).

Current-controlled Output Current Source with 4 Input Channels LVDS Compatible Inputs, Channel 2, 3, and 4, with On-chip 100 Ω Termination Two Selectable Outputs for Grounded Laser Diodes Output Current per Channel up to 350 mA Total Output Current up to 500 mA On-chip RF Oscillator Control of 2 Different Swings and Frequencies by Use of 4 External Resistors Oscillator Frequency Range fr.
