4. POWER SUPPLIES
The CS5376A has three sets of power supply in-
puts. Two sets supply power to the I/O pins of the
device (VDD1, VDD2), and the third supplies
power to the logic core (VD). The I/O pin power
supplies determine the maximum input and output
voltages when interfacing to peripherals, and the
logic core power supply largely determines the
power consumption of the CS5376A.
