TL071 JFET-Input Op-Amp

@@ -0,0 +1,54 @@+# TL071++**Texas Instruments** · Operational Amplifier · SOIC-8++The TL071 is a single operational amplifier with JFET inputs, giving very low input bias current and high input impedance. It is a general-purpose choice for active filters, integrators, sample-and-hold circuits, and audio signal conditioning.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | NC | unconnected | No internal connection. Leave floating or tie to a quiet net. On the PS (SO-8) TL071C variant this pin is instead OFFSET N1 for external offset-null trim. |+| 2 | IN- | input | Inverting input to the op-amp. High-impedance JFET gate input; common-mode range (VCC-) - 0.5 V to (VCC+) + 0.5 V. Diode-clamped to both supply rails on new-die (H-suffix) parts; limit swing currents to <=10 mA. |+| 3 | IN+ | input | Noninverting input to the op-amp. High-impedance JFET gate input; common-mode range extends to the positive rail (VCC+). Diode-clamped to both supply rails on new-die parts. |+| 4 | VCC- | power_in | Negative supply rail. Connect to the negative supply in a dual-supply system (typ. -15 V), or to GND in a single-supply system. Total supply span VS = (VCC+) - (VCC-) up to 36 V (42 V on non-NS/PS packages). |+| 5 | NC | unconnected | No internal connection. On the PS (SO-8) TL071C variant this pin is instead OFFSET N2 for external offset-null trim (typ. 10 kΩ pot between OFFSET N1 and OFFSET N2 with wiper to VCC-). |+| 6 | OUT | output | Op-amp output. Class-AB output with continuous short-circuit protection to ground (one amplifier per package). Typical output swing rails-to within a few hundred mV of supply. |+| 7 | VCC+ | power_in | Positive supply rail. Connect to the positive supply (typ. +15 V). Decouple with a 0.1 µF ceramic to VCC- (or to GND for single-supply) close to the pin. |+| 8 | NC | unconnected | No internal connection. Leave floating or tie to a quiet net. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Single JFET-input op-amp |+| Supply voltage | +-2.25 V to +-18 V (4.5 V to 36 V single) |+| Input bias current | 30 pA typ |+| Slew rate | 13 V/us typ |+| Gain-bandwidth product | 3 MHz typ |+| Input offset voltage | 3 mV typ |+| Operating temperature | 0 C to 70 C |++## Ordering variants++- `TL071P`+- `TL071D`+- `TL071PS`+- `TL071DBV`+- `TL071DCK`++## CAD (KiCad official)++- Symbol: `tl071.kicad_sym`+- Footprint: `tl071.kicad_mod`+- 3D model: SOIC-8 body from KiCad `Package_SO/SOIC-8_3.9x4.9mm_P1.27mm`.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tl071.pdf) (89 pp, sha256 `40b14981bad45917`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
