# TL971IDR

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

TL971IDR 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; the datasheet identifies this pin as NC on the D package. |
| 2 | IN- | input | Inverting input; the recommended common-mode input voltage range is VCC- + 1.15 V to VCC+ - 1.15 V. |
| 3 | IN+ | input | Non-inverting input; the recommended common-mode input voltage range is VCC- + 1.15 V to VCC+ - 1.15 V. |
| 4 | VCC- | power_in | Negative supply rail; the recommended total supply voltage VCC is 2.7 V to 12 V. |
| 5 | NC | unconnected | No internal connection; the datasheet identifies this pin as NC on the D package. |
| 6 | OUT | output | Amplifier output with rail-to-rail swing (±2.4 V at VCC = ±2.5 V); input and output voltages must never exceed VCC+ + 0.3 V. |
| 7 | VCC+ | power_in | Positive supply rail; recommended supply voltage 2.7 V to 12 V, absolute maximum supply 15 V. |
| 8 | NC | unconnected | No internal connection; the datasheet identifies this pin as NC on the D package. |

## CAD (KiCad official)

- Symbol: `TL971IDR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tl971idr-etched.step` / `tl971idr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tl971idr.step` / `tl971idr.glb` are the bare package body.
