FUNCTION

Clamp Voltage Input. External potential used for voltage

clamping of VOUT.

Ground

Current-Monitor Output. OUT sources a current of 1/10th IREF.

Reference Current Output. REF provides the source current to

the cathode of the photodiode.

No Connection. Not internally connected.

Bias Voltage Input. Bias voltage for photodiode.

Current-Monitor Output. OUT presents a voltage proportional to

IREF at 1V/mA. An internal 10kΩ resistor connects OUT to GND

(see Functional Diagram).
