What is the accuracy of the thermistor bias current as a function of the supply voltage to which the bias resistor is connected? For example, what is the percentage change in bias current for, say, 1% and 5% changes in the supply voltage?
I would like to know if my laser diode is of type B and I want to use it in constant current mode. The anode of the LD is internally connected to the case. Now I would like the case to be grounded, how should I connect it with the WLD3343 LD Driver? Ground the anode and then connect the cathode to pin 11? Can pin 11 supply a negative voltage so that the LD can be lit up?
