8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s 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

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
