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 amplifier channel A. Rail-to-rail output; short-circuit current typically ±17mA; open-loop output resistance ~900Ω at 1MHz. |+| 2 | -IN A | input | Inverting input of amplifier channel A. High-impedance CMOS input; input bias current typically ±8pA (±15pA max at 25°C). Absolute limit: (V−)−0.5V to (V+)+0.5V. |+| 3 | +IN A | input | Non-inverting input of amplifier channel A. Input common-mode range extends from (V−)−0.1V to (V+)−2V (extendable to V+ with reduced performance). |+| 4 | V- | power_in | Negative supply rail (or ground in single-supply operation). Total specified supply range V+ to V-: +2.7V to +36V (±1.35V to ±18V dual-supply). |+| 5 | +IN B | input | Non-inverting input of amplifier channel B. Same common-mode range as channel A. |+| 6 | -IN B | input | Inverting input of amplifier channel B. High-impedance CMOS input matching channel A characteristics. |+| 7 | OUT B | output | Output of amplifier channel B. Rail-to-rail output, matching channel A drive characteristics. |+| 8 | V+ | power_in | Positive supply rail. Specified supply range +2.7V to +36V referenced to V-. Quiescent current typically 110µA per amplifier (145µA max). |++## 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.++- `OPA2170AIDR`+- `OPA2170AIDRAIDGK`+- `OPA2170AIDRAIDGKR`+- `OPA2170AIDRAIDCUT`+- `OPA2170AIDRAIDCUR`++## CAD (KiCad official)++- Symbol: `OPA2170AIDR`+- 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/opa2170a.pdf) (34 pp, sha256 `1dd37a606fb5874b`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
