# OP07DDR

**Texas Instruments** · Precision OpAmps · SOIC-8

OP07DDR from Texas Instruments, in a SOIC-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 tied to VCC+ (typ. 20 kOhm) to null the input offset voltage. |
| 2 | IN- | input | Inverting input of the operational amplifier. High input impedance; common-mode input range +/-13 V (typ) with VCC = +/-15 V. |
| 3 | IN+ | input | Noninverting input of the operational amplifier. High input impedance; common-mode input range +/-13 V (typ) with VCC = +/-15 V. |
| 4 | VCC- | power_in | Negative supply pin. Recommended operating range -3 V to -18 V (absolute maximum -22 V). Can also be tied to GND for single-supply operation. |
| 5 | NC | unconnected | No internal connection. Do not connect (leave floating). |
| 6 | OUT | output | Amplifier output. Peak output voltage typ. +/-13 V into RL >= 10 kOhm at VCC = +/-15 V; short-circuit protected to ground or either supply for unlimited duration. |
| 7 | VCC+ | power_in | Positive supply pin. Recommended operating range 3 V to 18 V (absolute maximum 22 V). |
| 8 | OFFSET N2 | input | External input offset voltage adjustment. Connect a potentiometer between OFFSET N1 and OFFSET N2 with the wiper tied to VCC+ (typ. 20 kOhm) to null the input offset voltage. |

## CAD (KiCad official)

- Symbol: `OP07DDR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `op07ddr-etched.step` / `op07ddr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `op07ddr.step` / `op07ddr.glb` are the bare package body.
