APPLICATION INFORMATION

macromodel information

Macromodel information provided was derived using Microsim Parts

 Release 8, the model generation

software used with Microsim PSpice

. The Boyle macromodel (see Note 2) and subcircuit in Figure 54 are

generated using the TLV246x 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):

D Maximum positive output voltage swing

D Maximum negative output voltage swing

D Slew rate

D Quiescent power dissipation

D Input bias current

D Open-loop voltage amplification

D Unity-gain frequency

D Common-mode rejection ratio

D Phase margin

D DC output resistance

D AC output resistance

D Short-circuit output current limit
