1. Description  
The T0816 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 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  
250 mA to the total output current of up to 300 mA. A total gain of 100 (read channel),  
250 (channel 2) and 150 (channel 3) are provided between each reference current  
input and the output. Although the reference inputs are current inputs voltage control  
is possible by using external resistors.  
An on-chip RF oscillator is provided to reduce laser mode hopping noise during read  
mode. Frequency and swing can be set by two external resistors. Oscillation is  
enabled by a ‘high’ at the ENOSC pin. Complete output current and oscillator switch-  
off is achieved by a ‘low’ at the ENABLE input.
