OPERATIONAL AMPLIFIER(OP-AMP)
.

, Introduction
Operational amplifiers are linear devices that have all the
properties required for nearly ideal DC amplification. They
are used extensively in signal conditioning, filtering or to
perform mathematical operations such as add, subtract,
integration and differentiation.
An Operational Amplifier, or op-amp , is fundamentally a
voltage amplifying device designed to be used with external
feedback components such as resistors and capacitors between
its output and input 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,
the amplifier can perform a variety of different operations,
2 giving rise to its name of “Operational Amplifier”.
