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

necessary level shifting. If the Ref In pin is not used for level
shifting, then it must be grounded to maintain high CMR.
THEORY OF OPERATION
Refer to the figure on the first page. For 0 to 5V output with
4–20mA input, the required transimpedance of the circuit is:
GAIN AND OFFSET ADJUSTMENT
V
OUT/IIN = 5V/16mA = 0.3125V/mA.
Figure 2 shows the circuit for adjusting the RCV420 gain.
Increasing the gain of the RCV420 is accomplished by
inserting a small resistor in the feedback path of the ampli-
fier. Increasing the gain using this technique results in CMR
degradation, and therefore, gain adjustments should be kept
as small as possible. For example, a 1% increase in gain is
typically realized with a 125Ω resistor, which degrades
CMR by about 6dB.
To achieve the desired output (0V for 4mA and 5V for
20mA), the output of the amplifier must be offset by an
amount:
VOS = –(4mA)(0.3125V/mA) = –1.25V.
The input current signal is connected to either +In or –In,
depending on the polarity of the signal, and returned to
ground through the center tap, CT. The balanced input—two
matched 75Ω sense resistors, RS—provides maximum rejec-
tion of common-mode voltage signals on CT and true differ-
ential current-to-voltage conversion. The sense resistors
convert the input current signal into a proportional voltage,
which is amplified by the differential amplifier. The voltage
gain of the amplifier is:
A decrease in gain can be achieved by placing matched
resistors in parallel with the sense resistors, also shown in
Figure 2. The adjusted gain is given by the following
expression
V
OUT/IIN = 0.3125 x RX /(RX + RS).
A 1% decrease in gain can be achieved with a 7.5kΩ
resistor. It is important to match the parallel resistance on
each sense resistor to maintain high CMR. The TCR mis-
match between the two external resistors will effect gain
error drift and CMR drift.
AD = 5V/(16mA)(75Ω) = 4.1667V/V.
The tee network in the feedback path of the amplifier
provides a summing junction used to generate the required
–1.25V offset voltage. The input resistor network provides
high-input impedance and attenuates common-mode input
voltages to levels suitable for the operational amplifier’s
common-mode signal capabilities.
There are two methods for nulling the RCV420 output offset
voltage. The first method applies to applications using the
internal 10V reference for level shifting. For these applica-

Figure 1 shows the proper connections for power supply and
signal. Both supplies should be decoupled with 1µF tanta-
lum capacitors as close to the amplifier as possible. To avoid
gain and CMR errors introduced by the external circuit,
connect grounds as indicated, being sure to minimize ground
resistance. The input signal should be connected to either
+In or –In, depending on its polarity, and returned to ground
through the center tap, CT. The output of the voltage refer-
ence, Ref Out, should be connected to Ref In for the

tions, the voltage reference output trim procedure can be
used to null offset errors at the output of the RCV420. The
voltage reference trim circuit is discussed under “Voltage
Reference.”
using the Rcv Com pin. It is important to use a low-output
impedance amplifier to maintain high CMR. With this method
of zero adjustment, the Ref In pin must be connected to the
Rcv Com pin.
When the voltage reference is not used for level shifting or
when large offset adjustments are required, the circuit in
Figure 3 can be used for offset adjustment. A low impedance
on the Rcv Com pin is required to maintain high CMR.
MAINTAINING COMMON-MODE REJECTION
Two factors are important in maintaining high CMR: (1)
resistor matching and tracking (the internal resistor network
does this) and (2) source impedance. CMR depends on the
accurate matching of several resistor ratios. The high accu-
racies needed to maintain the specified CMR and CMR
temperature coefficient are difficult and expensive to reli-
ably achieve with discrete components. Any resistance im-
balance introduced by external circuitry directly affects
CMR. These imbalances can occur by: mismatching sense
resistors when gain is decreased, adding resistance in the
feedback path when gain is increased, and adding series
resistance on the Rcv Com pin.
ZERO ADJUSTMENT
Level shifting the RCV420 output voltage can be achieved
using either the Ref In pin or the Rcv Com pin. The
disadvantage of using the Ref In pin is that there is an 8:1
voltage attenuation from this pin to the output of the RCV420.
Thus, use the Rcv Com pin for large offsets, because the
voltage on this pin is seen directly at the output. Figure 4
shows the circuit used to level-shift the output of the RCV420
The two sense resistors are laser-trimmed to typically match
within 0.01%; therefore, when adding parallel resistance to
decrease gain, take care to match the parallel resistance on
each sense resistor. To maintain high CMR when increasing
the gain of the RCV420, keep the series resistance added to
the feedback network as small as possible. Whether the Rcv
Com pin is grounded or connected to a voltage reference for
level shifting, keep the series resistance on this pin as low as
possible. For example, a resistance of 20Ω on this pin
degrades CMR from 86dB to approximately 80dB. For
applications requiring better than 86dB CMR, the circuit
shown in Figure 5 can be used to adjust CMR.

PROTECTING THE SENSE RESISTOR

The 75Ω sense resistors are designed for a maximum con-
tinuous current of 40mA, but can withstand as much as
250mA for up to 0.1s (see absolute maximum ratings).
There are several ways to protect the sense resistor from

For a system operating off of a 32V supply RX = 725Ω and

power JFET and source resistor are used as a current limit.
The 200Ω potentiometer, RX, is adjusted to provide a current
limit of approximately 30mA. This circuit introduces a
1–4V drop at full scale. If only a very small series voltage
drop at full scale can be tolerated, then a 0.032A series 217

VOLTAGE REFERENCE
The RCV420 contains a precision 10V reference. Figure 8
shows the circuit for output voltage adjustment. Trimming
the output will change the voltage drift by approximately
0.007ppm/°C per mV of trimmed voltage. Any mismatch in
TCR between the two sides of the potentiometer will also
affect drift, but the effect is divided by approximately 5. The
trim range of the voltage reference using this method is
typically ±400mV. The voltage reference trim can be used to
trim offset errors at the output of the RCV420. There is an
8:1 voltage attenuation from Ref In to Rcv Out, and thus the
trim range at the output of the receiver is typically ±50mV.

Request Application Bulletin AB-014 for details of a

The high-frequency noise (to 1MHz) of the voltage refer-
ence is typically 1mVp-p. When the voltage reference is
used for level shifting, its noise contribution at the output of
the receiver is typically 125µVp-p due to the 8:1 attenuation
from Ref In to Rcv Out. The reference noise can be reduced
by connecting an external capacitor between the Noise
Reduction pin and ground. For example, 0.1µF capacitor
reduces the high-frequency noise to about 200µVp-p at the
output of the reference and about 25µVp-p at the output of
the receiver.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
