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 in Figure 59 were generated using
the TLC227x typical electrical and operating characteristics at T = 25°C. Using this information, output
A
simulations of the following key parameters can be generated to a tolerance of 20% (in most cases):
