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.
