Product details
Overview
RCV420JPG4 from Texas Instruments (formerly Burr-Brown) is a precision monolithic 4–20mA current-loop receiver IC that converts industrial loop current into a 0–5V output voltage with 0.1% overall conversion accuracy, ±40V common-mode input range, and 86dB CMR. It integrates premium op-amps, laser-trimmed 75Ω sense resistors, and a 10V reference for factory-calibrated performance in process control signal conditioning.
For engineers reviewing the RCV420JPG4 datasheet, RCV420JPG4 pinout, RCV420JPG4 application, or RCV420JPG4 equivalent, this page delivers verified technical context, exact pin functions, real-world application cards, and two validated alternative parts - all grounded in the official TI SBVS019 datasheet and packaging documentation for the RCV420JP grade in 16-pin PDIP.
Technical Context
The RCV420JPG4 implements a differential transimpedance architecture using matched internal 75Ω sense resistors and a high-precision op-amp to achieve 0.3125 V/mA gain (5V span over 16mA range). Its tee-network feedback provides built-in –1.25V offset for true 0V-out-at-4mA operation without external trimming.
It features an integrated 10V reference (5ppm/°C drift, 5µVp-p 0.1Hz–10Hz noise) with Ref In and Ref Trim pins enabling level-shifting and offset nulling. The ±40V common-mode input range and 86dB CMR are maintained only when external circuitry preserves resistor matching and low-impedance grounding at Rcv Com and Ref Com.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (–In) | Inverting current input terminal | Accepts negative-polarity 4–20mA loop return; paired with +In for balanced differential sensing |
| 2 (+In) | Non-inverting current input terminal | Accepts positive-polarity 4–20mA loop feed; matched 75Ω sense resistor to –In ensures CMR |
| 3 (CT) | Center-tap return node | Loop current return path; must connect to system ground or isolated return to complete 2-wire loop |
| 4 (V+) | Positive power supply | Accepts +11.4V to +18V; requires local 1µF tantalum decoupling for stability and noise immunity |
| 5 (Ref Com) | Reference circuit ground | Dedicated low-impedance ground for 10V reference; must be tied to system ground or isolated reference plane |
| 7 (Ref Noise Reduction) | Noise filter terminal | Connect 0.1µF capacitor to ground to reduce 10V reference HF noise from 1mVp-p to ~200µVp-p |
| 8 (Ref Trim) | Reference output adjustment | Enables ±4% trimming of 10V reference; used for system-level offset nulling via 8:1 attenuation to output |
| 10 (Ref fB) | Reference feedback | Internal node for reference amplifier feedback; not user-accessible; leave unconnected |

| 12 (Ref In) | Reference level-shift input | Accepts external voltage to shift RCV420 output zero point; 8:1 attenuation to output (±1V in = ±125mV out) |
| 13 (Rcv Com) | Receiver output common | Direct zero-adjust node; voltage applied here appears 1:1 at Rcv Out; must be low-impedance for CMR integrity |
| 14 (Rcv Out) | Main 0–5V output | Final converted voltage; drives loads up to 1000pF; 0.01Ω differential output impedance |
| 15 (Rcv fB) | Receiver feedback | Internal amplifier feedback node; not user-accessible; leave unconnected |
| 16 (V–) | Negative power supply | Accepts –11.4V to –18V; requires local 1µF tantalum decoupling adjacent to pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4–20mA receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XTR115IRUGT | Two-wire 4–20mA transmitter (not receiver); lacks integrated 0–5V output, reference, or sense resistors | Used on field device side to drive loop; cannot replace RCV420JPG4 in control room or PLC input stage | Select only if designing loop-powered sensor - not for receiving existing 4–20mA signals |
| ISO122JP | Isolated precision voltage-output converter; requires external 4–20mA-to-voltage front-end and separate isolation power | Provides galvanic isolation (1500Vrms), but adds complexity, cost, and footprint vs. RCV420JPG4's direct interface | Choose when ground loop elimination or safety isolation is mandatory; otherwise RCV420JPG4 offers simpler, lower-cost solution |
Compared with XTR115IRUGT (a transmitter IC) and ISO122JP (an isolated voltage converter), the RCV420JPG4 uniquely delivers self-contained, non-isolated 4–20mA-to-0–5V conversion with factory-trimmed accuracy - reducing design time, component count, and calibration effort in industrial I/O modules.

FAQ
What is the operating temperature range for RCV420JPG4?
The RCV420JPG4 is specified for 0°C to +70°C operation, matching the JP-grade qualification defined in the TI SBVS019 datasheet. It supports storage from –40°C to +85°C and has a thermal resistance (θJA) of 80°C/W in its 16-pin PDIP package. This range aligns with standard industrial control cabinet environments but excludes extended-temperature applications requiring –40°C to +85°C operation (e.g., RCV420KP or RCV420BG variants).
Does RCV420JPG4 require external resistors for basic 4–20mA to 0–5V conversion?
No, RCV420JPG4 requires no external resistors for nominal 4–20mA to 0–5V conversion. Its internal laser-trimmed 75Ω sense resistors, precision op-amp, and 10V reference provide full functionality with only power supply decoupling (1µF tantalum per rail) and proper grounding. External resistors are optional only for gain/offset adjustments - which degrade CMR and are unnecessary for standard applications.
How does the RCV420JPG4 achieve 0V output at 4mA input?
The RCV420JPG4 achieves 0V output at 4mA through an internal tee-network feedback configuration that injects a –1.25V offset (4mA × 0.3125 V/mA) into the amplifier summing junction. This offset cancels the 1.25V developed across the 75Ω sense resistor at 4mA, resulting in precisely 0V at Rcv Out - all without external components or trimming.
Can RCV420JPG4 be used with a 24V loop supply?
Yes, RCV420JPG4 is compatible with standard 24V industrial loop supplies. Its 1.5V full-scale voltage drop (at 20mA) leaves 22.5V headroom for transmitter compliance - well above the typical 12–15V requirement of most 2-wire transmitters. Absolute maximum supply is ±22V, confirming safe operation within 24V loop margins even with line transients.
What is the purpose of the Ref In and Rcv Com pins on RCV420JPG4?
The Ref In pin accepts an external voltage to level-shift the RCV420JPG4 output zero point with 8:1 attenuation (e.g., +1V on Ref In yields +125mV at Rcv Out), while the Rcv Com pin provides direct 1:1 zero adjustment - ideal for large offsets. Both require low-impedance drive to preserve CMR; Ref In must be grounded if unused, and Rcv Com must never include series resistance exceeding 20Ω.
