APPLICATION INFORMATION
macromodel information
Macromodel information provided was derived using PSpice Parts model generation software. The Boyle
macromodel (see Note 4) and subcircuit in Figure 58 were generated using the TLE208x typical electrical and
operating characteristics at T_A = 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 Maximum negative output voltage swing
D Slew rate
D Quiescent power dissipation
D Input bias current
D Open-loop voltage amplification
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
