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

OPA364IDR 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 internal connection (can be left floating). |
| 2 | -IN | input | Negative (inverting) input. |
| 3 | +IN | input | Positive (noninverting) input. |
| 4 | V- | power_in | Negative (lowest) power supply. |
| 5 | NC | unconnected | No internal connection (can be left floating). |
| 6 | VOUT | output | Output. |
| 7 | V+ | power_in | Positive (highest) power supply. |
| 8 | NC | unconnected | No internal connection (can be left floating). |

## CAD (KiCad official)

- Symbol: `OPA364IDR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `opa364idr-etched.step` / `opa364idr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa364idr.step` / `opa364idr.glb` are the bare package body.
