@@ -0,0 +1,52 @@+# TL072++**Texas Instruments** · Dual JFET-input op-amp · SOIC-8++A dual JFET-input operational amplifier in a SOIC-8, a longtime favorite for audio and active filters. The JFET front end gives very high input impedance and low input bias current, so it does not load high-impedance sources, and it pairs a 3 MHz gain-bandwidth with a fast 13 V/us slew rate and low noise. Two independent amplifiers share the split supply, which runs up to plus/minus 18 V. It is the go-to op-amp for guitar pedals, mixers, and Sallen-Key filters.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | 1OUT | output | Output of amplifier channel 1. Push-pull class-AB output with short-circuit protection; can drive typical op-amp loads within ±(VCC−headroom). |+| 2 | 1IN- | input | Inverting input of amplifier channel 1. High-impedance JFET gate input; low input bias current. |+| 3 | 1IN+ | input | Noninverting input of amplifier channel 1. High-impedance JFET gate input; common-mode input range includes VCC+. |+| 4 | VCC- | power_in | Negative supply rail. Connect to −2.25 V to −20 V (split supply) or GND (single supply). Total supply span 4.5 V to 40 V. |+| 5 | 2IN+ | input | Noninverting input of amplifier channel 2. High-impedance JFET gate input; common-mode input range includes VCC+. |+| 6 | 2IN- | input | Inverting input of amplifier channel 2. High-impedance JFET gate input; low input bias current. |+| 7 | 2OUT | output | Output of amplifier channel 2. Push-pull class-AB output with short-circuit protection. |+| 8 | VCC+ | power_in | Positive supply rail. Connect to +2.25 V to +20 V (split supply) or 4.5 V to 40 V (single supply). Bypass to VCC− with 100 nF close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Dual JFET-input op-amp |+| Gain-bandwidth | 3 MHz |+| Slew rate | 13 V/µs |+| Input impedance | very high (JFET) |+| Input bias current | typ. 65 pA |+| Supply voltage | ±3 to ±18 V |+| Channels | 2 independent |+| Package | SOIC-8 |++## Ordering variants++- `TL072CD (SOIC-8, tube)`+- `TL072CDR (SOIC-8, tape & reel)`++## CAD (KiCad official)++- Symbol: `Amplifier_Operational:TL072`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tl072.pdf) (89 pp, sha256 `40b14981bad45917`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
