The device supports a wide range of operation on its analog supply. The AVDD can operate from 3 V to 5.5 V. The DVDD operates from 1.65 V to 5.5 V, independent of the AVDD supply. A voltage regulator available on the PAMBoard is used to create a regulated 5-V supply for the EVM. AVDD is created from this supply using a low-dropout (LDO) voltage regulator to create a clean +3.3 V. DVDD is provided directly from the PAMBoard at 3.3 V. There is an option to use an external power supply for DVDD through J2.
