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 | OUT A | output | Output of channel A op-amp. Rail-to-rail output stage capable of driving loads within a few tens of mV of either supply rail. |+| 2 | -IN A | input | Inverting input of channel A. High-impedance CMOS input; input common-mode range includes the negative supply rail. |+| 3 | +IN A | input | Noninverting input of channel A. High-impedance CMOS input; MUX-friendly architecture prevents inrush current under large differential inputs. |+| 4 | V- | power_in | Negative (lowest) power supply. Single-supply operation 4.5 V to 36 V, or split-supply ±2.25 V to ±18 V referenced to V+. |+| 5 | +IN B | input | Noninverting input of channel B. High-impedance CMOS input; MUX-friendly architecture prevents inrush current under large differential inputs. |+| 6 | -IN B | input | Inverting input of channel B. High-impedance CMOS input; input common-mode range includes the negative supply rail. |+| 7 | OUT B | output | Output of channel B op-amp. Rail-to-rail output stage capable of driving loads within a few tens of mV of either supply rail. |+| 8 | V+ | power_in | Positive (highest) power supply. Wide supply range 4.5 V to 36 V single-supply. Quiescent current 1.7 mA max per channel-pair. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `OPA2189IDRIDR`+- `OPA2189IDRID`+- `OPA2189IDRIDGKR`+- `OPA2189IDRIDGK`++## CAD (KiCad official)++- Symbol: `OPA2189IDR`+- 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/opa2189.pdf) (58 pp, sha256 `0d8a997989aeb646`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
