Precision 4mA To 20mA Current Loop Receiver

The RCV420 is a precision current-loop receiver designed 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 premium 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, which is useful in loops containing extra instrument burdens or in intrinsically safe applications where transmitter compliance voltage is at a premium. The 10V reference provides a precise 10V output with a typical drift of 5ppm/?C.The RCV420 is completely self-contained and offers a highly versatile function. No adjustments are needed for gain, offset, or CMR. This provides three important advantages over Discrete board-level designs: 1) lower initial design cost, 2) lower manufacturing cost, and 3) easy, cost-effective field repair of a precision circuit.
