2.2 Power Requirements

The EVMs are equipped with a DC socket (J_VDD) for easy connection of power. The positive supply input is labeled +5V, the ground supply input is labeled GND. The +5V is also connected to a test point TP1, which can be used for connecting power supply using clip connector. The EVM can safely operates from 3V to 5.25V supply but please note this device and hence the EVM does not support split-supply operation. Buy default three supply decaps C1, C2, C3 are connected at the Vcc pins. This along with R1 forms a low pass filter at supply. A ferrite bead FB1 is also connected to filter out high freq noise at the supply. This supply filter is important to get good PSRR performance from the device.
