Pin Description

PIN NAME

1

VCC

Supply Voltage

2

N.C.

No Connection. Not internally connected.

3

IN

Amplifier Input

FUNCTION

4

FILTER

Provides bias voltage for the photodiode through a 1.5kΩ resistor to VCC. When grounded, this pin disables

the DC Cancellation Amplifier to allow a DC path from IN to OUT+ and OUT- for testing.

5

GND Ground

6

OUT- Inverting Output. Current flowing into IN causes VOUT- to decrease.

7

OUT+ Noninverting Output. Current flowing into IN causes VOUT+ to increase.

8

GND Ground
