What Is the TL082? JFET-Input Dual Op-Amp and Uses
The TL082 is a JFET-input, dual-channel op-amp. With high input impedance and low input current it is the wider-bandwidth relative of the TL072; used in active filters, buffers and general analog circuits. It is pin-compatible with the TL072: the TL072 is lower-noise (audio), the TL082 has wider bandwidth. It is not rail-to-rail.
The TL082 is a JFET-input, dual-channel op-amp. With high input impedance and low input current it is the wider-bandwidth/faster relative of the TL072; common in audio and general analog circuits. For the concept, see what is an op-amp.
What is the TL082 used for?
Active filters, buffers, signal amplification, sample-and-hold and general analog processing. Its JFET input reads high-impedance sources (sensors, piezo) without loading them. It runs from a single or dual (±) supply.
Specifications
| Parameter | Value |

Watch out
The TL082 and TL072 are pin-compatible; the TL072 is lower-noise (preferred for audio), the TL082 has wider bandwidth. It is not rail-to-rail; the output won't reach the supply rails. For single-supply use the input needs a reference (half-supply).
Equivalents
- TL072: pin-compatible, low-noise sibling (audio).
