Considerations for Selecting a Power Amplifier
Application Note 302 is intended to assist people who are not power amplifier experts and tounderstand the basic parameters necessary to properly select one for use in testing and experimentation. A wide range of scientific disciplines, from mechanical engineering to biology and chemistry, use amplifiers in research and test. Amplifiers simply increase the size of a signal by some factor greater than 1 and are nece sary when a signal source does not produce an output level sufficient for the task at hand. To select the right amplifier, it is important to unde stand some of the different param ters and how they affect the perfomance.
