I want to calculate the power consumption of the following components to ensure that my design doesn't crosses certain power limit so kindly help me out with the necessary details as I am little confused with the datasheet values.
A) I want supply voltage and supply current values to calculate power.
B) Kindly provide me typical values which can help me reduce power consumption of my system.
C) Also tell me if there is any necessity to use negative voltage or dual supply and risks involved if only positive voltage is used.
D) Provide me a solution about voltage supplies to enhance the overall performance of these components.
