Three band active tone control with TL 082-N

TL 082-N Wide Bandwidth dual JFET input Operational Amplifier

This device is low cost, high speed, dual JFET input operational amplifier with an internally trimmed input offset voltage (BI-FET II™ technology). They require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input
bias and offset currents. The TL082 is pin compatible

with the standard LM1558 allowing designers to immediately upgrade the overall performance of existing LM1558 and most LM358 designs.
