Leave floating or tie to a convenient net; not electrically connected to the die. |+| 2 | Inverting Input | input | Inverting input of the current-feedback op-amp. Typical inverting input bias current ±2µA; inverting input impedance ~30Ω (open-loop). Connect the feedback resistor R_F (nominally 402Ω) between this pin and the Output pin. |+| 3 | Noninverting Input | input | Noninverting (+) input of the current-feedback op-amp. Typical noninverting input bias current ±5µA; input impedance 280kΩ || 1.2pF. Common-mode input range ±2.5V typical on ±5V supplies. |+| 4 | -Vs | power_in | Negative supply rail. Typical operating supply ±5V; absolute maximum ±6.5V. Bypass with local decoupling capacitors close to the pin. |+| 5 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net. |+| 6 | Output | output | Op-amp output. Delivers ±80mA typical output current with ±3.4V output swing into 100Ω load on ±5V supplies. Short-circuit current ±200mA typical. |+| 7 | +Vs | power_in | Positive supply rail. Typical operating supply ±5V; absolute maximum ±6.5V. Bypass with local decoupling capacitors close to the pin. |+| 8 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net. |++## 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.++- `OPA694IDR`+- `OPA694IDRIDBVT`+- `OPA694IDRIDBVR`++## CAD (KiCad official)++- Symbol: `OPA694IDR`+- 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/opa694.pdf) (31 pp, sha256 `1ab0fc7590bf7ecf`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
