# UA741CP

**Texas Instruments** · Operational Amplifier · PDIP-8

UA741CP from Texas Instruments, in a PDIP-8. 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 N1 | input | External input offset voltage adjustment. Connect a potentiometer between OFFSET N1 and OFFSET N2 with the wiper to VCC- to null the input offset voltage (typ 1 mV, max 6 mV). |
| 2 | IN- | input | Inverting input of the op-amp. High-impedance input (ri typ 2 MOhm); input bias current typ 80 nA, max 500 nA. Common-mode input voltage range +/-12 V min at VCC = +/-15 V. |
| 3 | IN+ | input | Noninverting input of the op-amp. High-impedance input (ri typ 2 MOhm); input bias current typ 80 nA. Differential input voltage rated +/-15 V (UA741C). |
| 4 | VCC- | power_in | Negative supply rail. Recommended range -5 V to -15 V; absolute maximum -18 V (UA741C). Supply current typ 1.7 mA, max 2.8 mA. |
| 5 | OFFSET N2 | input | External input offset voltage adjustment. Pair with OFFSET N1: connect a low-value potentiometer between OFFSET N1 and OFFSET N2 with the wiper tied to VCC-. |
| 6 | OUT | output | Op-amp output. Short-circuit protected (Ios typ +/-25 mA, max +/-40 mA). Maximum output voltage swing +/-14 V typ into RL >= 10 kOhm at VCC = +/-15 V; output resistance ~75 Ohm. |
| 7 | VCC+ | power_in | Positive supply rail. Recommended range +5 V to +15 V; absolute maximum +18 V (UA741C). Decouple locally with a bypass capacitor to VCC-. |
| 8 | NC | unconnected | No internal connection. Do not connect. |

## CAD (KiCad official)

- Symbol: `UA741CP`
- Footprint: `Package_DIP:DIP-8_W7.62mm`
- 3D model: PDIP-8 (KiCad packages3D, STEP)
- 3D model files: `ua741cp-etched.step` / `ua741cp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ua741cp.step` / `ua741cp.glb` are the bare package body.
