7.1.4 4mA-to-20mA Output

The XTR111 does not provide internal circuits to generate 4mA with 0V input signal. Figure 7-3 shows that the most common way to shift the input signal is a two-resistor network connected to a voltage reference and the signal source. This arrangement allows easy adjustment for overrange and underrange conditions. The example assumes a 5V reference (VREF) that equals the full-scale signal voltage and a signal span of 0V to 5V for 4mA-to-20mA (IMIN to IMAX) output.

The voltage regulator output or a more precise reference can be used as VREF. Observe the potential drift added by the drift of the resistors and the voltage reference.
