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

THS4081CDR 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, as stated in the datasheet pin legend. |
| 2 | IN− | input | Inverting input of the THS4081 single-channel voltage-feedback amplifier (block diagram, Figure 1); no pin-specific voltage limit is given in this excerpt. |
| 3 | IN+ | input | Noninverting input of the THS4081 single-channel voltage-feedback amplifier (block diagram, Figure 1); no pin-specific voltage limit is given in this excerpt. |
| 4 | VCC− | power_in | Negative supply rail; the device is specified for dual supplies from VCC = ±5 V to ±15 V. |
| 5 | NC | unconnected | No internal connection, as stated in the datasheet pin legend. |
| 6 | OUT | output | Amplifier output, specified with high output drive capability of IO = 85 mA (typ). |
| 7 | VCC+ | power_in | Positive supply rail; the device is specified for dual supplies from VCC = ±5 V to ±15 V. |
| 8 | NC | unconnected | No internal connection, as stated in the datasheet pin legend. |

## CAD (KiCad official)

- Symbol: `THS4081CDR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `ths4081cdr-etched.step` / `ths4081cdr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ths4081cdr.step` / `ths4081cdr.glb` are the bare package body.
