Description

1

P1

Noninverting Input. A 10 kΩ resistor is connected to the noninverting (+) terminal of the op amp.

2

P2

Noninverting Input. A 10 kΩ resistor is connected to the noninverting (+) terminal of the op amp.

3

P3

Noninverting Input. A 20 kΩ resistor is connected to the noninverting (+) terminal of the op amp. This pin

is used as a reference voltage input in many configurations.
