Abstract: This design idea describes a simple circuit that converts a 4-20mA signal to a 0V to 5V analog voltage ideal for conversion to digital with an analog-to-digital converter (ADC). The 4mA level from the transducer produces a 0V output and the 20mA level produces a 5V output. A current sense amplifier generates this analog 0V to 5V output. In addition, the circuit provides a comparator output that can be used to detect a zero current condition.
