The RCV420 is a precision current-loop receiver de-signed to convert a 4–20mA input signal into a 0–5V
output signal. As a monolithic circuit, it offers high reliability at low cost. The circuit consists of a pre-
mium grade operational amplifier, an on-chip precision resistor network, and a precision 10V reference. The
RCV420 features 0.1% overall conversion accuracy, 86dB CMR, and ±40V common-mode input range.
The circuit introduces only a 1.5V drop at full scale.
