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 N1 | input | Offset null pin 1. Connect one end of an external 20 kΩ potentiometer here; the wiper goes to VCC+ to trim the input offset voltage. |+| 2 | IN- | input | Inverting input of the op-amp. Common-mode input voltage range ±13 V typ at VCC±=±15 V; input bias current ±1.8 nA typ. |+| 3 | IN+ | input | Non-inverting input of the op-amp. Common-mode input voltage range ±13 V typ at VCC±=±15 V; input bias current ±1.8 nA typ. |+| 4 | VCC- | power_in | Negative supply rail. Operating range -3 V to -18 V (referenced to VCC+ midpoint); absolute maximum -22 V. |+| 5 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net. |+| 6 | OUT | output | Op-amp output. Peak output voltage ±13 V typ into RL ≥ 10 kΩ; output may be shorted to ground or either supply indefinitely. |+| 7 | VCC+ | power_in | Positive supply rail. Operating range +3 V to +18 V; absolute maximum +22 V. Also serves as the reference for the offset-null potentiometer wiper. |+| 8 | OFFSET N2 | input | Offset null pin 2. Connect the other end of the external 20 kΩ potentiometer here; potentiometer wiper returns to VCC+ for offset-voltage trimming. Adjustment range ±4 mV. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `OP07CDRD`+- `OP07CDRDR`+- `OP07CDRP`++## CAD (KiCad official)++- Symbol: `OP07CDR`+- 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/op07c.pdf) (15 pp, sha256 `c68e9ffdd5c60c1c`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
