Overview
The TL084CPWR is a quad JFET-input operational amplifier produced by Texas Instruments. It is part of the TL08xH family, which are next-generation versions of the industry-standard TL08x devices. These amplifiers are designed to provide outstanding value for cost-sensitive applications, featuring low offset voltage, high slew rate, and a wide range of common-mode and differential voltage ranges.
The TL084CPWR is particularly suited for rugged and demanding applications due to its high ESD tolerance (1.5 kV, HBM), integrated EMI and RF filters, and operational temperature range from –40°C to 125°C.
