Pin Description

N.C.

No Connection

Amplifier Input

FILTER

Provides bias voltage for the photodiode through a 1.5k

Ω 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.

GND

Ground

OUT-

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

OUT+

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

GND

Ground
