LASER DIODE MODULATOR

Figure 6 is a minimum component count example of a video

modulator for a CW laser diode This example biases the

volt of signal If it is desired to reduce power consumption

change R2 to 5 kX and R4 to 15X

CAPACITIVE LOAD DRIVING

Figure 7 is the circuit used to demonstrate the ability of the

LM6313 to drive capacitive loads at speeds not previously

possible with monolithic op amps
