APPLICATION NOTE 722
3V/5V DACs Support Intelligent Current Loop

Abstract: This application note explains 4-20mA current loops and intelligent transmitters and explains their
need for high-resolution low-power DACs.


An optimum power-supply chip is not the only critical choice to be made in designing a mixed 3V/5V
microprocessor-controlled system. Because more and more systems require low-power components capable of
low-voltage startup, state-of-the-art A/……
