# OP07CDTR

**XBLW** · Operational Amplifier · SOP-8

OP07CDTR from XBLW, in a SOP-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 N1 | passive | Offset null pin 1, used for input offset voltage trimming (optional null per the block diagram). |
| 2 | IN- | input | Inverting input of the operational amplifier. |
| 3 | IN+ | input | Non-inverting input of the operational amplifier. |
| 4 | V- | power_in | Negative supply pin; supply range is ±2.5V to ±22V. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Amplifier output. |
| 7 | V+ | power_in | Positive supply pin; supply range is ±2.5V to ±22V. |
| 8 | OFFSET N2 | passive | Offset null pin 8, used for input offset voltage trimming (optional null per the block diagram). |

## CAD (KiCad official)

- Symbol: `OP07CDTR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `op07cdtr-etched.step` / `op07cdtr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `op07cdtr.step` / `op07cdtr.glb` are the bare package body.
