APPLICATION INFORMATION
Macromodel Information
Macromodel information provided was derived using Microsim Parts, the model generation software used with
Microsim PSpice. The Boyle macromodel
(2)
and subcircuit in Figure 59 are generated using the TLC227x 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):

Journal of Solid-State Circuits, SC-9, 353 (1974).
