LF351 is a single operational amplifier with an internally compensated input offset voltage. It also provides wide bandwidth, low input bias current, and offset current. Basically, this IC is used in circuits that need high input impedance, high speed integrators, Quick digital to analog converters, sample and hold circuits, etc. The IC is always available in an 8 – pin hermetically sealed dual in line (DIP) IC packaging. LF351 op – amp offers many different features such as high input impedance, high slew rate, low power dissipation, and high noise immunity. The IC has a wide range of working voltages and can directly be interfaced with

Operational Amplifier

An operational amplifier is a voltage amplifying device; which can boost up a weak electronic signal to a higher level. Operational amplifiers are designed with the intention to be used with external feedback components such as resistors and capacitors between its I/O terminals. These feedback components determine the resulting function or “operation” of the amplifier and by virtue of the different feedback configurations whether resistive, capacitive, or both.
