Idealized Op Amp Limited
Idealized operational amplifier with limited output
Description
Equations
Connections
Parameters
The Idealized Op Amp Limited component models an 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.
The supply voltage is either defined by parameters Vps and Vns or by (optional) pins sp and sn. In the first case the necessary power is drawn from an implicit internal supply, in the second case from the external supply.
The strict parameter, when true, applies noEvent to the conditional expression.
