3V/5V DACs Support Intelligent Current Loop
Overview 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/D and D/A converters with near-ideal specifications, including 3V/5V operation, are also welcome. Today's popular industrial-control applications, such as programmable-logic controllers, factory process control, computer numeric control (CNC), and intelligent transmitters, all demand low-power semiconductors. Consistent with this trend is the use of 4mA-to20mA current loops, which have become a well-established part of the analog communications between the host computer and smart transmitters in a factory environment. This article describes intelligent transmitters and explains their need for high-resolution low-power D/A converters.
