Description

Because of its immunity to noise voltage drops and line resistance the 4?20mA current loop has become the standard for analog signal transmission in the process control industry. The RCV420 is the first one-chip solution for converting a 4?20mA signal into a precision 0?5V output. Although the on-chip current sensing resistor is designed to tolerate moderate overloads it can be damaged by large
