@@ -0,0 +1,58 @@+# TL074++**Texas Instruments** · Quad JFET-input op-amp · SOIC-14++Four JFET-input operational amplifiers in one SOIC-14, the quad version of the TL072. The JFET front end gives very high input impedance and low bias current, paired with a 3 MHz gain-bandwidth, a fast 13 V/us slew rate, and low noise. With four amplifiers in a package it suits multi-stage audio (mixers, active crossovers, multi-band EQ), instrumentation front ends, and banks of Sallen-Key filters. All four share the split supply, which runs up to plus/minus 18 V.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | 1OUT | output | Amplifier 1 output.
