The TL084IDR from Texas Instruments is a quad JFET Operational Amplifier (Op Amp) with a negative input. It features four independent, high-voltage, high-gain amplifiers in a single IC package. The TL084IDR allows designers to take advantage of the improved noise performance, low offset values, fast settling time, and reduced input power common with JFET’s. Each amplifier in the the quad package contains an input offset voltage null facility, with optional compensation for the errors associated with long, high-capacitance cables. This device has a wide operating temperature range of -40°C to +125°C and is suitable for use in a variety of medical, automotive, and industrial applications.
