Overview
The TL082CM/NOPB is a wide bandwidth dual JFET input operational amplifier produced by Texas Instruments. It is part of the BI-FET II™ technology family, known for its low cost, high speed, and internally trimmed input offset voltage. This amplifier is designed to offer low supply current while maintaining a large gain bandwidth product and a fast slew rate. It is pin compatible with the LM1558, allowing designers to upgrade the performance of existing LM1558 and most LM358 designs easily.
