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 | NC | unconnected | No internal connection. May be left floating or tied to any voltage between V- and V+. |+| 2 | -IN | input | Inverting input of the op-amp. Common-mode input range extends to (V-)+1.5 V and up to (V+)-2 V; input bias current typ ±60 nA. |+| 3 | +IN | input | Non-inverting input of the op-amp. Common-mode input range extends to (V-)+1.5 V and up to (V+)-2 V; input bias current typ ±60 nA. |+| 4 | V- | power_in | Negative supply rail. Operates from -18 V to -2.25 V for split supplies, or 0 V (GND) for single-supply operation up to 36 V total across V+ and V-. Bypass to V+ with 0.1 µF ceramic close to the pins. |+| 5 | NC | unconnected | No internal connection. May be left floating or tied to any voltage between V- and V+. |+| 6 | OUT | output | Rail-to-rail amplifier output. Sources/sinks up to ±30 mA short-circuit; output swings to within ~600 mV of each rail at 10 mA load. Slew rate 27 V/µs. |+| 7 | V+ | power_in | Positive supply rail. Operates from +2.25 V to +18 V for split supplies, or 4.5 V to 36 V single-supply (referenced to V-). Bypass to V- with 0.1 µF ceramic close to the pins. Typical supply current 3.6 mA per channel. |+| 8 | Shutdown | input | Active-high shutdown control. Device enabled when (V-) ≤ V_SHUTDOWN ≤ (V+)-3 V; device disabled when V_SHUTDOWN ≥ (V+)-0.35 V. Reduces supply current when asserted. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `OPA211AIDR`+- `OPA211AIDRAIDGK`+- `OPA211AIDRAIDGKT`+- `OPA211AIDRAIDGKR`+- `OPA211AIDRG`+- `OPA211AIDRGT`+- `OPA211AIDRGR`++## CAD (KiCad official)++- Symbol: `OPA211AIDR`+- 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/opa211a.pdf) (None pp, sha256 `2b9cee692757525c`, retrieved 2026-08-17, tier: manufacturer)+- **Datasheet language:** Chinese.
