LF355 is a junction field effect transistor input operational amplifier IC. The IC features low input bias and offset currents/low offset voltage and offset voltage drift, coupled with offset adjust which does not degrade drift or common mode rejection. The IC is always available in an 8 – pin hermetically sealed dual in line IC package (DIP). LF355 has a wide range of working conditions, a wide array of operating voltages, and is compatible with almost every TTL, CMOS, & PMOS device. The IC also offers many different features such as high input impedance and high noise immunity.
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 amplifier 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.
