APPLICATION INFORMATION
TLE2227 macromodel information
Macromodel information provided was derived using Microsim Parts™, the model generation software used
with Microsim PSpice ™. The Boyle macromodel (see Note 6) and subcircuit in Figure 49 and Figure 50 are
generated using the TLE2227C typical electrical and operating characteristics at 25°C. Using this information,
output simulations of the following key parameters can be generated to a tolerance of 20% (in most cases):
D Maximum positive output voltage swing
D Unity-gain bandwidth
D Maximum negative output voltage swing
D Common-mode rejection ratio
D Slew rate
D Phase margin
D Quiescent power dissipation
D DC output resistance
D Input bias current
D AC output resistance
D Open-loop voltage amplification
D Short-circuit output current limit
