# TL071CDTR

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

TL071CDTR 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 terminal 1 of the amplifier, shown on the symbol as the first offset null connection. |
| 2 | IN- | input | Inverting input; absolute input voltage max ±15 V, differential input max ±30 V, common-mode range (Vcc-)+1.5 V to (Vcc+)-0.5 V. |
| 3 | IN+ | input | Non-inverting input; absolute input voltage max ±15 V, differential input max ±30 V, common-mode range (Vcc-)+1.5 V to (Vcc+)-0.5 V. |
| 4 | VCC- | power_in | Negative supply pin; total supply voltage rating is ±18 V. |
| 5 | OFFSET N2 | passive | Offset null terminal 2 of the amplifier, shown on the symbol as the second offset null connection. |
| 6 | OUT | output | Amplifier output with short-circuit protection; typical peak swing ±13.5 V into RL = 10 kΩ at Vcc = ±15 V. |
| 7 | VCC+ | power_in | Positive supply pin; total supply voltage rating is ±18 V. |
| 8 | NC | unconnected | No internal connection. |
