Bluetooth Noise Resolved w/ 1205 Isolated DC Converter

Описание: Some quick notes on eliminating noise in a small amplifier circuit that utilizes a stand alone bluetooth module. In this case, the BT module is running at 5 volts while the amplifier is running at 12 volts.

We will examine the noise implications of decreasing the voltage for the BT module when using: (1) a step down buck converter, (2) an LM7805 linear power regulator, and, (3) a 1205S isolated dc to dc regulator.
