NAME
OUT+
FUNCTION
Noninverting Data Output. Current flowing into IN causes the voltage at OUT+ to increase.
2, 3
V
CC
+3.3V Supply Voltage. The pads are not internally connected. Therefore, they must always be externally
bonded.
4
FILT
Provides bias voltage for the photodiode through a 750
resistor to V
CC
. When grounded, this pin disables
the DC-cancellation amplifier to allow a DC path from IN to OUT+ and OUT- for testing.
5
IN
TIA Input. Signal current from photodiode flows into this pin.
6
MON
Photocurrent Monitor. Output current from MON is proportional to the average current in R
FILT
. Connect a
resistor between MON and ground to monitor the average photocurrent.
7, 11

9
GND
N.C.
OUT-
Circuit Ground. The pads are not internally connected. Therefore, they must always be externally bonded.
No Connection
Inverting Data Output. Current flowing into IN causes the voltage at OUT- to decrease.
