Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Idealized operational amplifier with saturation:

  • Input currents are zero.
  • No-load amplification is high (but not infinite).
  • Output voltage is limited between positive and negative supply.

Supply voltage is either defined by parameter Vps and Vns or by (optional) pins s_p and s_n.

In the first case the necessary power is drawn from an implicit internal supply, in the second case from the external supply.
