5.5 Special Function
These are a group of analog devices that are used for the following applications:
• instrumentation amplifier
• video amplifier
• multiplier/divider
• preamplifier
• active filter
• high precision reference
5.5.1 Special Function: Simulation models
The same levels of simulation model as the opamps are provided with several levels of
simulation models of increasing complexity and accuracy.
The following model levels are used to distinguish between these models:
• L1 - this is the simplest model with the opamp modeled as a gain block with a differential
input and a single ended output.
• L2 - this is a more complex model in which the supply voltages are included in the
simulation.
• L3 - this is a model of increasing complexity where additional control pins are supported.
• L4 - this is the most complex and accurate model with a majority of the external control
pins modeled.
