One-chip data acquisition gives elbow room to analog signals

You can talk about digital fieldbus and wireless Ethernet. But there's nothing like good old analog signal over a 4-20 mA loop for transmitting data between process and control equipment—though engineers are using some unusual tools to help them create ever smaller and more powerful analog peripheral boards and boxes.
