Overview
The TL084HIDR is a high-performance, quad operational amplifier from 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 rates, and wide supply voltage ranges. The TL084HIDR is particularly suited for demanding applications due to its integrated EMI and RF filters, high ESD protection, and operation across a wide temperature range of –40°C to 125°C.
