	<h3>Summary</h3>
	<p>Transmit 12 bit audio using Teensy 3.1's built-in digital to analog converter.</p>
	<h3>Audio Connections</h3>

	<h3>Functions</h3>
	<p>This object has no functions to call from the Arduino sketch.  It
		simply streams data from the ADC to its output port.</p>
	<h3>Hardware</h3>
	<p align=center><img src="img/dacpin.jpg"></p>
	<p>Signal range is 0 to 1.2V</p>
	<p>Most applications require at least a 10&micro;F DC-blocking capacitor.</p>
	<p>TODO: photo of Teensy 3.1 with 10&micro;F capacitor and 3.5mm jack.</p>

	<h3>Notes</h3>
	<p>The output rate is 44.1 kHz (no oversampling).  Ultrasonic noise present if
		not filtered.  This may not
		be an issue for many uses, but care should be used if amplified and driven
		to high power tweeters.</p>
