**Texas Instruments** · Precision Op Amps · PDIP-8

OPA37GP from Texas Instruments, in a PDIP-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 | Offset Trim | input | Input offset voltage trim pin; leave floating if not used. |
| 2 | -In | input | Inverting input. |
| 3 | +In | input | Non-inverting input. |
| 4 | V- | power_in | Negative (lowest) power supply. |
| 5 | NC | unconnected | No internal connection; can be left floating. |
| 6 | Output | output | Amplifier output. |
| 7 | V+ | power_in | Positive (highest) power supply. |
| 8 | Offset Trim | input | Input offset voltage trim pin; leave floating if not used. |

## CAD (KiCad official)

- Symbol: `OPA37GP`
- Footprint: `Package_DIP:DIP-8_W7.62mm`
- 3D model: PDIP-8 (KiCad packages3D, STEP)
- 3D model files: `opa37gp-etched.step` / `opa37gp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa37gp.step` / `opa37gp.glb` are the bare package body.
