Texas Instruments · Operational Amplifier · SOIC-14
The TL084 packs four JFET-input operational amplifiers into a single 14-pin body. The JFET inputs give high input impedance and low bias current, and the 13 V/us slew rate suits active filter banks, multichannel signal conditioning, and audio. It is the quad member of the TL08x family.
Pinout
