APPLICATION INFORMATION

macromodel information

Macromodel information provided was derived using Microsim

Parts

™, the model generation software used

with Microsim

PSpice

™. The Boyle macromodel (see Note 5) and subcircuit in73, Figure 74, and Figure 75 were

generated using the TLE202x 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 Unity-gain frequency

D Common-mode rejection ratio

D Phase margin

D DC output resistance

D AC output resistance

D Short-circuit output current limit

D Maximum positive output voltage swing

D Maximum negative output voltage swing

D Slew rate

D Quiescent power dissipation

D Input bias current

D Open-loop voltage amplification
