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.
