LF411 is a Low offset drift JFET input Operational Amplifier. The device utilizes JFET input operational amplifiers with very low input offset voltage and guaranteed input offset voltage drift. They require a low supply current yet maintain a large gain bandwidth product and fast slew rate. The IC always comes in an 8 – pin hermetically sealed dual in line IC package (DIP), and is compatible with almost every JFET, CMOS, BiMOS device.
JFET Operational Amplifier
JFET (Junction field effect transistor) operational amplifier is a simple electronic configuration that boost up a voltage of lower strength to a higher level. Operational amplifiers are usually designed to be used with external feedback components such as resistors and capacitors. Operational amplifiers are commonly used in devices such as home theatre systems, VCRs, PCs, Laptops, etc. JFET operational amplifiers are also an essential feature for many audio instrumentation tools such as a decibel meter (dB meter).
