Pin Description

PIN

NAME

FUNCTION

1

VCC

+3.3V Supply Voltage

2

IN

Signal Input. Connect to photodiode anode.

Optional Filter Connection. Use to bias the photodiode cathode. An internal on-chip resistive network

3

FILT

is connected between this pin and VCC; an external decoupling capacitor connected to this pin forms

a filter (see the Design Procedure section). Leave this pin open if a filter is not required.

4

MON

Optional Photocurrent Monitor. This is a current output. Connect a resistor between MON and ground

to monitor the average photocurrent. Leave this pin open if a monitor is not required.

5, 8

GND

Circuit Ground

6

OUT+ Positive 75Ω Data Output. Increasing input current causes OUT+ to increase.

7

OUT-

Negative 75Ω Data Output. Increasing input current causes OUT- to decrease.
