<description>&lt;h3&gt;SparkFun Amplifiers&lt;/h3&gt;
This library contains analog amplifiers, mostly operational amplifiers but also has some headphone and audio amps with more specific applications.
&lt;p&gt;Contents:
&lt;ul&gt;&lt;li&gt;Op-amps&lt;/li&gt;
&lt;li&gt;Headphone amps&lt;/li&gt;
&lt;li&gt;Class D amps&lt;/li&gt;
&lt;/ul&gt;&lt;/p&gt;
&lt;br&gt;
We've spent an enormous amount of time creating and checking these footprints and parts, but it is &lt;b&gt; the end user's responsibility&lt;/b&gt; to ensure correctness and suitablity for a given componet or application. 
&lt;br&gt;
&lt;br&gt;If you enjoy using this library, please buy one of our products at &lt;a href=" www.sparkfun.com"&gt;SparkFun.com&lt;/a&gt;.

You are welcome to use this library for commercial purposes. For attribution, we ask that when you begin to sell your device using our footprint, you email us with a link to the product being sold. We want bragging rights that we helped (in a very small part) to create your 8th world wonder. We would like the opportunity to feature your device on our homepage.</description>
