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 | Output 1 | output | Op-amp 1 output. All-NPN output stage with symmetrical source/sink current (typ 30 mA), drives 0 to 10,000 pF capacitive loads. Output swing 13.4 V to -14.7 V with +-15 V supplies into 2 kOhm. |+| 2 | Inputs 1 (-) | input | Op-amp 1 inverting input. Darlington PNP input stage; input bias current typ 100 nA, differential input resistance typ 150 MOhm, input offset voltage 1.0 mV typ / 5.0 mV max (non-A suffix). |+| 3 | Inputs 1 (+) | input | Op-amp 1 non-inverting input. Common-mode input range extends from VEE to (VCC - 1.8 V), enabling true single-supply operation with ground-referenced signals. |+| 4 | VEE | power_in | Negative supply / ground rail. Tie to GND for single-supply operation (3.0 V to 44 V total supply) or to a negative rail for split-supply use with |VCC|+|VEE| <= 44 V. |+| 5 | Inputs 2 (+) | input | Op-amp 2 non-inverting input. Common-mode input range extends from VEE to (VCC - 1.8 V). |+| 6 | Inputs 2 (-) | input | Op-amp 2 inverting input. Darlington PNP input stage; input bias current typ 100 nA. |+| 7 | Output 2 | output | Op-amp 2 output. All-NPN output stage, output short-circuit current typ 30 mA source and sink, indefinite short-circuit duration. |+| 8 | VCC | power_in | Positive supply rail. 3.0 V to 44 V single-supply, or +-22 V split. Quiescent current per amplifier is typ 1.9 mA (2.5 mA max) at +-15 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `MC34072VDR2GD`+- `MC34072VDR2G`+- `MC34072VDR2GP`++## CAD (KiCad official)++- Symbol: `MC34072VDR2G`+- 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:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mc34072v-d.pdf) (26 pp, sha256 `bac1389f1389705f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
