Pin Description

PIN NAME

FUNCTION

1

VCC

Supply-Voltage Input

2

IN

Signal Input

3

INREF Input Reference Connection. Connect to photodetector AC ground.

4, 5

GND Ground

6

OUT- Inverting Voltage Output. Current flowing into the input causes OUT- to decrease.

7

OUT+ Noninverting Voltage Output. Current flowing into the input causes OUT+ to increase.

Compensation Capacitor Connection. Connection for optional external compensation capacitor for DC-

8

COMP cancellation circuit. Add capacitance here to reduce the low-frequency cutoff of the DC cancellation circuit.

Connect COMP directly to GND to disable the DC cancellation circuit.

FILTER

Filter Connection. Provides positive bias for photodiode through a 1kΩ resistor to VCC (see the Designing

Filters section). Available on the die only.
