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

OPA690IDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connection. |
| 2 | IN- | input | Inverting input with maximum ±1.2V differential input voltage absolute rating. |
| 3 | IN+ | input | Noninverting input with maximum ±1.2V differential input voltage absolute rating. |
| 4 | -VS | power_in | Negative power supply pin for 5V to 12V total supply operation. |
| 5 | NC | unconnected | No connection. |
| 6 | Output | output | Output provides maximum 215mA output current with ±3.9V voltage swing. |
| 7 | +VS | power_in | Positive power supply pin for 5V to 12V total supply operation. |
| 8 | DIS | input | Disable control pin; low state disables op amp with 100µA supply current and high-impedance output. |

## CAD (KiCad official)

- Symbol: `OPA690IDR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `opa690idr-etched.step` / `opa690idr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa690idr.step` / `opa690idr.glb` are the bare package body.
