QWhat is the exact power-supply sequence? How long does it take?
AAt power-up, the part resets all the internal registers, loads half scale in
the RDAC and proceeds to read the EEPROM. Once the EEPROM is correctly read
back, the part loads the new RDAC value into the register. Typically the
power-up sequence takes 50uS, while reset after the part is already powered up
is a little faster at 30uS.
