The MCP6061/2/4 op amps can be used in gyrator
applications. The gyrator is an electric circuit which can
make a capacitive circuit behave inductively.

applications. The primary application for a gyrator is to
reduce the size and cost of a system by removing the
need for bulky, heavy and expensive inductors. For
example, RLC bandpass filter characteristics can be
realized with capacitors, resistors and operational
amplifiers without using inductors. Moreover, gyrators
will typically have higher accuracy than real inductors,
due to the lower cost of precision capacitors than
inductors.
