NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TIâs customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
8.1.1 Macromodel Information
Macromodel information provided was derived using Microsim Parts, the model generation software used with
Microsim PSpice. The Boyle macromodel (1) and subcircuit in Figure 46 are generated using the TLC227x typical
electrical and operating characteristics at TA = 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
⢠Unity-gain frequency
⢠Common-mode rejection ratio
⢠Phase margin
⢠DC output resistance
⢠AC output resistance
⢠Short-circuit output current limit
