II II TCA580
INTEGRATED GYRATOR CIRCUIT
The TCA580 is a monolithic integrated gyrator Circuit with floating inputs. It is intended
mainly to replace the coils in telephony low-pass filters. The simulated inductance
consists of the IG, two resistors Rg1 and Rg2 and a capaCitor C2. With this configuration,
inductances of up to 1 MH ± 2% can be achieved.
