DUAL AXIS PSD SUM AND DIFFERENCE AMPLIFIER SPECIFICATION
The DL100-7PCBA3 is a dual axis position sensing diode with sum and difference amplifiers. It contains internal bias circuitry of 14.3 volts for the position sensing diode, or the user can externally apply a bias voltage. The board has a 9 pin connector for easy hook up.
Outputs are bipolar voltage analogs of the X and Y position of the light spot centroid, as well as the total X current and the total Y current. The sum outputs may be used to externally normalize the X and Y difference outputs. By normalizing the X and Y signals, they become independent of fluctuations in light spot intensity.
