Overview
The TL082CPG4, although listed as obsolete, is part of the TL082 family of general-purpose JFET input dual operational amplifiers produced by Texas Instruments. These devices are known for their high performance and versatility in various applications. The TL082 series is an enhancement of the industry-standard TL08x devices, offering improved features such as high slew rates, low offset voltage, and wide common-mode and differential voltage ranges. These amplifiers are suitable for cost-sensitive applications and can operate in rugged and demanding environments due to their high ESD tolerance and integrated EMI and RF filters.
