# TL971QDRQ1

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

TL971QDRQ1 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. |
| 2 | IN- | input | Inverting input; differential input voltage limited to ±1 V and input range VCC- - 0.3 V to VCC+ + 0.3 V. |
| 3 | IN+ | input | Noninverting input; differential input voltage limited to ±1 V and input range VCC- - 0.3 V to VCC+ + 0.3 V. |
| 4 | VCC- | power_in | Negative supply (ground in single-supply use); total supply voltage 2.7 V to 12 V recommended. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Rail-to-rail amplifier output, typically swinging ±2.4 V at VCC = ±2.5 V; must never exceed VCC + 0.3 V. |
| 7 | VCC+ | power_in | Positive supply; total supply voltage 2.7 V to 12 V recommended (15 V absolute maximum). |
| 8 | NC | unconnected | No internal connection. |
