I have a question about the power consumption on the AD8400 digital potentiometer. The datasheet gives supply current for CMOS and TLL:
Can you explain what this means. Is this talking about the current the entire part draws assuming the SDO line (on AD8403) is connected to a TTL/CMOS input?
How much current can expect a AD8400ARZ1 to draw during normal operation and during and immediate following a write to its register? I'm trying to work out whether I can get away with powering this part with a resistor divider and how low the values in the divider must be.
