		+	The '''LM386''' is a low-power amplifier chip. It is able to directly drive a small speaker, and is thus used in a number of battery-powered practice amp designs.
		+
		+	==Voltage reference trick==
		+	The LM386 has a self-centering output voltage. In other words, if there's no signal at it inputs, its output sits at half the supply voltage. Because of this, the 386 can be used as a source of a buffered [[bias voltage]] in stompbox circuits.
