RCV420KP

Description
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.
