T0810 Datasheet | Atmel

3-Channel Laser Driver with RF Osc. and APC Amplifier Description .. The T0810 is a laser diode driver for the operation of a grounded laser diode for CD-RW drives. 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. Write current pulses are enabled when a ‘low’ signal is applied to the NE Pins. All channels are summed together at the IOUT Pin. Each channel can contribute up to 150 mA to the total output current of up to 200 mA. A total gain of 400 mA is provided...
