Many industrial current-loop data acquisition systems operate
on a 24V or 28V single supply. You can make a singlesupply
current loop receiver with the RCV420 by using its
10V reference as a pseudo ground. The RCV420 will convert
a 4-20mA loop current into a 0 to 5V output voltage
with no external components required. The current loop can
be sourcing or sinking and can be referenced to either the
power-supply V+ or ground.
