Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | Offset Trim | input | Input offset voltage trim pin. Connect a 10 kΩ potentiometer between pins 1 and 8 with the wiper to V- to adjust the initial input offset voltage. Leave floating if not used. |+| 2 | -In | input | Inverting input of the operational amplifier. High-impedance analog input with typical bias current of 1 nA maximum. |+| 3 | +In | input | Noninverting input of the operational amplifier. High-impedance analog input with typical bias current of 1 nA maximum. |+| 4 | V- | power_in | Negative (lowest) power supply. Operating range from -2 V to -18 V for split-supply operation, referenced to V+ across a total supply of 4 V to 36 V. |+| 5 | NC | unconnected | No internal connection. Can be left floating. |+| 6 | Output | output | Operational amplifier output. Class-AB output stage capable of driving typical loads with low distortion; short-circuit protected. |+| 7 | V+ | power_in | Positive (highest) power supply. Operating range from +2 V to +18 V for split-supply operation; total V+ to V- supply span 4 V to 36 V. |+| 8 | Offset Trim | input | Input offset voltage trim pin. Connect a 10 kΩ potentiometer between pins 1 and 8 with the wiper to V- to adjust the initial input offset voltage. Leave floating if not used. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `OPA277UU`+- `OPA277UP`+- `OPA277UDRM`++## CAD (KiCad official)++- Symbol: `OPA277U`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/opa277u.pdf) (43 pp, sha256 `0d85011c5df09178`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
