Overview
The TL084IN is a high-speed JFET input quad operational amplifier produced by Texas Instruments. It is part of the TL08x family, which includes next-generation versions of the industry-standard TL08x devices. This amplifier is 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 TL084IN is particularly suited for rugged and demanding applications due to its high ESD protection, integrated EMI and RF filters, and operation across a wide temperature range of –40°C to 125°C.
