This schematic below was built using a 2-layer evaluation board for the AD9662 3-Channel Laser Diode Driver,this device are used mainly for high performance CD-DVD recordable drives and laser diode current switching.
you choose dc logic levels on the enable pins, use all Jumper W1
through Jumper W5 while Resistor R6 through Resistor R11 should not be installed. Otherwise, when you desired an external signal sources on the enable pins, used all these resistors while the jumper is disabled.
