Rail-to-rail output stage capable of swinging within 18 mV of either supply rail under light load. |+| 2 | -IN A | input | Channel A inverting input. High-impedance input with RFI filtering and typical bias current of 250 pA. |+| 3 | +IN A | input | Channel A noninverting input. Input common-mode range includes the negative rail; RFI-filtered high-impedance input. |+| 4 | V- | power_in | Negative power supply (or GND for single-supply operation). Total supply range 4 V to 36 V (±2 V to ±18 V split). |+| 5 | +IN B | input | Channel B noninverting input. Input common-mode range includes the negative rail; RFI-filtered high-impedance input. |+| 6 | -IN B | input | Channel B inverting input. High-impedance input with RFI filtering and typical bias current of 250 pA. |+| 7 | OUT B | output | Channel B amplifier output. Rail-to-rail output stage capable of swinging within 18 mV of either supply rail under light load. |+| 8 | V+ | power_in | Positive power supply. Total supply range 4 V to 36 V (±2 V to ±18 V split). Bypass with a 100 nF capacitor close to the pin. |++## 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.++- `OPA2180IDR`+- `OPA2180IDRIDGK`+- `OPA2180IDRIDGKR`++## CAD (KiCad official)++- Symbol: `OPA2180IDR`+- 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/opa2180.pdf) (49 pp, sha256 `82193759582a36f1`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
