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 are generated using
the TLV2721 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).
