| Pin | Signal | Type | Function & connection |
|---|---|---|---|
| OFFSET1 | Offset adjustment | One end of the optional offset-null network.Connection guidanceLeave open in the basic example. Use the manufacturer trim circuit when offset adjustment is required. | |
| IN− | Inverting input | Negative feedback input.Connection guidanceConnect to the 90 kΩ / 10 kΩ feedback junction. | |
| IN+ | Non-inverting input | Positive signal input.Connection guidanceApply the 0.20 V input signal relative to the supply midpoint. | |
| V− | Negative supply | Negative power rail.Connection guidanceConnect to −15 V; bypass locally to the 0 V midpoint. This is not ground in the illustrated split-supply circuit. | |
| OFFSET2 | Offset adjustment | Other end of the optional offset-null network.Connection guidanceLeave open in the basic example. | |
| OUT | Analog output | Amplified output signal.Connection guidanceConnect the 90 kΩ feedback resistor and a high-impedance meter. Output needs headroom from both supply rails. | |
| V+ | Positive supply | Positive power rail.Connection guidanceConnect to +15 V; bypass locally to the 0 V midpoint. | |
| NC | No connection | No electrical connection is specified for this contact.Connection guidanceLeave unconnected. |
