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 | OUTA | output | Output of channel A op-amp. Rail-to-rail output, swings within 1 mV of V+/V- rails with a 100 kΩ load. |+| 2 | -INA | input | Inverting (negative) input of channel A op-amp. Rail-to-rail input, common-mode range extends 500 mV beyond each supply rail. |+| 3 | +INA | input | Non-inverting (positive) input of channel A op-amp. Rail-to-rail input. |+| 4 | V+ | power_in | Positive (highest) power supply. Single-supply operation from 2.5 V up to 5.5 V (absolute-max supply span typically 7 V). Decouple with 0.1 µF near the pin. |+| 5 | +INB | input | Non-inverting (positive) input of channel B op-amp. Rail-to-rail input. |+| 6 | -INB | input | Inverting (negative) input of channel B op-amp. |+| 7 | OUTB | output | Output of channel B op-amp. Rail-to-rail output. |+| 8 | OUTC | output | Output of channel C op-amp. Rail-to-rail output. |+| 9 | -INC | input | Inverting (negative) input of channel C op-amp. |+| 10 | +INC | input | Non-inverting (positive) input of channel C op-amp. |+| 11 | V- | power_in | Negative (lowest) power supply. Tie to ground for single-supply operation, or to a negative rail for split-supply use. |+| 12 | +IND | input | Non-inverting (positive) input of channel D op-amp. |+| 13 | -IND | input | Inverting (negative) input of channel D op-amp. |+| 14 | OUTD | output | Output of channel D op-amp. Rail-to-rail output. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOP-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++- `OPA4340UAUA`++## CAD (KiCad official)++- Symbol: `OPA4340UA`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOP-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/opa4340ua-datasheet.pdf) (18 pp, sha256 `e75e687924f6aa75`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
