DESCRIPTION

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 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 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.

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
