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 | OFFSET_NULL1 | input | Offset null 1. Connect an external trim potentiometer between OFFSET_NULL1 (pin 1) and OFFSET_NULL2 (pin 5) with the wiper tied to VCC- to trim input offset voltage (typ 1 mV, max 5 mV at 25 °C). |+| 2 | IN- | input | Inverting input of the op-amp. High-impedance analog input (Ri typ 2 MΩ, min 0.3 MΩ). Common-mode input range ±12 V at VCC = ±15 V. |+| 3 | IN+ | input | Non-inverting input of the op-amp. High-impedance analog input (Ri typ 2 MΩ, min 0.3 MΩ). Common-mode input range ±12 V at VCC = ±15 V. |+| 4 | VCC- | power_in | Negative supply rail. Typical dual-supply operation ±15 V; absolute maximum ±22 V. Total supply range 5 to 40 V. |+| 5 | OFFSET_NULL2 | input | Offset null 2. Second terminal of the external offset-trim potentiometer (paired with OFFSET_NULL1 on pin 1, wiper to VCC-). |+| 6 | OUT | output | Op-amp output. Class-AB output stage with internal short-circuit protection; output swing ±14 V typical at RL = 10 kΩ and VCC = ±15 V; short-circuit current typ 25 mA. |+| 7 | VCC+ | power_in | Positive supply rail. Typical dual-supply operation ±15 V; absolute maximum ±22 V. Total supply range 5 to 40 V; supply current typ 1.7 mA. |+| 8 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SO-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `UA741CDTD`+- `UA741CDTCDT`+- `UA741CDTN`+- `UA741CDTCN`++## CAD (KiCad official)++- Symbol: `UA741CDT`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SO-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/ua741cdt.pdf) (11 pp, sha256 `a9a423732c10edcf`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
