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
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OUT | output | Output of amplifier 1. |
| 2 | 1IN- | input | Inverting input of amplifier 1. |
| 3 | 1IN+ | input | Non-inverting input of amplifier 1. |
