5.1 Power

The power supply connections for the DYY-AMP-EVM can only be applied using the test points located at the top of the PCB. The positive power supply connection is labeled V+, the negative power supply connection is labeled V–, and the ground connection is labeled GND. For the minimum and maximum supply voltages of the DYY-AMP-EVM, please refer to the relevant device datasheet.

C1 and C2 act as local decoupling capacitors for the amplifier, populate to provide a low impedance return current path for the amplifier. Capacitors C15-C18 are bulk decoupling capacitors for the positive and negative supply rail.
