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 | +IN | input | Non-inverting input of the op-amp. Common-mode range extends 100mV beyond the negative rail and up to within 2V of the positive rail for normal operation. |+| 2 | V- | power_in | Negative supply rail. Total supply voltage V+ to V- must be between 4.5V and 36V (single-supply) or ±2.25V to ±18V (dual-supply). |+| 3 | -IN | input | Inverting input of the op-amp. Used with feedback network to set closed-loop gain. |+| 4 | OUT | output | Rail-to-rail output. Drives up to 1.6mA per amplifier at quiescent; capable of driving typical resistive and capacitive loads. |+| 5 | V+ | power_in | Positive supply rail. Total supply voltage V+ to V- must be between 4.5V and 36V (single-supply) or ±2.25V to ±18V (dual-supply). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SC-70-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `OPA172IDCKR`+- `OPA172IDCKRIDCKT`+- `OPA172IDCKRIDBVR`+- `OPA172IDCKRIDBVT`+- `OPA172IDCKRIDR`++## CAD (KiCad official)++- Symbol: `OPA172IDCKR`+- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`+- 3D model: SC-70-5 (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/opa172i.pdf) (51 pp, sha256 `8450068d24b46881`, retrieved 2026-08-17, tier: manufacturer)+- **Datasheet language:** Chinese.
