WHAT IF THE WORLD’S DATA CONSUMPTION DIDN’T ALSO CONSUME MOST OF THE WORLD’S POWER? Today’s data centers can require as much power as a small city. And that demand limits what businesses and industries can achieve. But what if power were unlimited? ADI breakthroughs in power efficiency are helping unlock a future without limits to computing power. Analog Devices. Where what if becomes what is. See What If: analog.com/WhatIf
