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 6) and subcircuit in Figure 57, Figure 58, and
Figure 59 were generated using the TLE20x7 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):
• Maximum positive output voltage swing
• Maximum negative output voltage swing
• Slew rate
• Quiescent power dissipation
• Input bias current
• Open-loop voltage amplification
• Gain-bandwidth product
• Common-mode rejection ratio
• Phase margin
• DC output resistance
• AC output resistance
• Short-circuit output current limit
