APPLICATION INFORMATION
macromodel information
Macromodel information provided was derived using PSpice ™ Parts ™ model generation software. The Boyle
macromodel (see Note 4) and subcircuit in Figure 58 are generated using the TLE2082 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):
• 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

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