APPLICATION INFORMATION
macromodel information
Macromodel information provided was derived using Microsim Partsâ¢, the model generation software used
with Microsim PSpice â¢. The Boyle macromodel (see Note 6) and subcircuit in Figure 57, Figure 58, and
Figure 59 were generated using the TLE20x7 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):
⢠Maximum positive output voltage swing
⢠Maximum negative output voltage swing
⢠Slew rate
⢠Quiescent power dissipation
⢠Input bias current
⢠Open-loop voltage amplification
⢠Gain-bandwidth product
⢠Common-mode rejection ratio
⢠Phase margin
⢠DC output resistance
⢠AC output resistance
⢠Short-circuit output current limit
