TLE2037 macromodel information
Macromodel information provided is derived using PSpice™ Parts™ model generation software. The Boyle
macromodel (see Note 6) and subcircuit in Figure 51 and Figure 52 are generated using the TLE2237C 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

Macromodels, simulation models, or other models provided by TI,
directly or indirectly, are not warranted by TI as fully representing all
of the specification and operating characteristics of the
semiconductor product to which the model relates.
