Product details
Overview
ADR520ARTZ-REEL7 from Analog Devices is a high-precision 2.048 V shunt voltage reference in SOT-23-3 package, featuring ±0.2% initial accuracy, 40 ppm/°C max temperature coefficient, 14 μVp-p low-frequency noise, and operation from 50 μA to 15 mA-designed for battery-powered instrumentation requiring stable, space-constrained analog references.
For engineers reviewing the ADR520ARTZ-REEL7 datasheet, ADR520ARTZ-REEL7 pinout, ADR520ARTZ-REEL7 application, or ADR520ARTZ-REEL7 equivalent, this page delivers verified specifications, trim-capable shunt topology details, industrial temperature range (−40°C to +85°C), and real-world use cases in portable data acquisition and precision power monitoring.
Technical Context
The ADR520ARTZ-REEL7 implements a bandgap-based shunt reference architecture with curvature-compensated ΔVBE summation to achieve low thermal drift. Its trim terminal enables ±0.5% output adjustment without degrading temperature coefficient performance.
It operates as a two-terminal device requiring only an external bias resistor, remains stable with any capacitive load, and delivers fast 2 μs turn-on settling-enabling direct integration into low-power ADC reference paths and portable sensor signal chains without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048 V nominal; precise value enables 12-bit DAC/ADC full-scale alignment without calibration. |
| Initial Accuracy | ±0.2% (Grade B); corresponds to ±4 mV tolerance at 25°C-suitable for high-fidelity measurement front-ends. |
| Tempco | 40 ppm/°C max over −40°C to +85°C; ensures ≤±0.8 mV drift across full industrial range. |
| Output Noise | 14 μVp-p (0.1–10 Hz); supports sub-16-bit resolution in low-frequency data acquisition systems. |
| Operating Current | 50 μA to 15 mA; ultra-low minimum current extends battery life in always-on sensing nodes. |

| Package | SOT-23-3 (RT-3); 2.9 mm × 1.3 mm footprint ideal for compact PCB layouts. |
Pinout & Package
ADR520ARTZ-REEL7 uses the standard 3-lead SOT-23-3 (RT-3) package per JEDEC TO-236-AB, with 1.0 mm pitch, 2.9 mm × 1.3 mm body, and 1.1 mm height. Pin 1 (V+) connects to the anode, Pin 2 (V−) to cathode, and Pin 3 (TRIM) provides voltage adjustment capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Anode input | Connects to bias resistor; sinks current to establish reference voltage at V− node. |
| V− | Cathode output | Provides stable 2.048 V reference potential; serves as ground-referenced output node. |
| TRIM | Adjustment terminal | Accepts external potentiometer or DAC to shift output ±0.5% while preserving tempco. |
Key Features
| Feature | Design Value |
|---|---|
| No external capacitor required | Stable with any capacitive load-eliminates layout constraints and reduces BOM count. |
| Pin-compatible with LM4040/LM4050 | Enables drop-in upgrade path for legacy designs seeking improved accuracy and lower noise. |
| Ultralow 50 μA minimum operating current | Extends runtime in coin-cell or energy-harvesting applications where quiescent current is critical. |
| Industrial temperature range | Validated operation from −40°C to +85°C-supports automotive cabin and industrial field deployments. |
| Trim-adjustable output | ±0.5% fine-tuning capability compensates for PCB trace resistance, ADC offset, or sensor gain errors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR520BRT-REEL7 | Same 2.048 V output, ±0.2% accuracy, 40 ppm/°C tempco, but non-RoHS-compliant SOT-23-3 packaging. | No trim terminal; fixed output only-lacks system-level calibration flexibility. | Select when RoHS compliance is not required and trim functionality is unnecessary. |
| LM4040C20IDBZR | 2.048 V output, ±0.5% initial accuracy, 100 ppm/°C tempco, no trim pin, higher 30 μVp-p noise. | Lower cost but reduced accuracy and stability-suitable for non-critical consumer-grade sensing. | Choose only for cost-sensitive applications where ±0.5% accuracy and >100 ppm/°C drift are acceptable. |
Compared with ADR520ARTZ-REEL7, ADR520BRT-REEL7 offers identical electrical specs but lacks RoHS compliance and trim capability, while LM4040C20IDBZR trades significant accuracy, stability, and noise performance for lower unit cost-making ADR520ARTZ-REEL7 optimal for calibrated industrial instrumentation.

FAQ
What is the output voltage tolerance of the ADR520ARTZ-REEL7 at 25°C?
The ADR520ARTZ-REEL7 has a Grade B initial accuracy of ±0.2%, corresponding to a 2.048 V output tolerance of ±4 mV at 25°C. This specification is guaranteed over the full production lot and validated per Analog Devices' ADR520B electrical characteristics table in Rev. E datasheet.
Does the ADR520ARTZ-REEL7 require an external capacitor for stability?
No, the ADR520ARTZ-REEL7 does not require an external capacitor for stability. Its internal design ensures unconditional stability with any capacitive load, eliminating the need for bypass capacitors on the V+ or V− terminals-a key advantage over older shunt references like the LM4040.
How is the TRIM pin used on the ADR520ARTZ-REEL7?
The TRIM pin on the ADR520ARTZ-REEL7 allows adjustment of the output voltage over a ±0.5% range using an external potentiometer or DAC. This feature enables system-level calibration to compensate for PCB trace resistance, ADC offset, or sensor gain errors without affecting the device's 40 ppm/°C temperature coefficient.
What is the minimum operating current for the ADR520ARTZ-REEL7?
The ADR520ARTZ-REEL7 has a guaranteed minimum operating current of 50 μA across the −40°C to +85°C industrial temperature range. This ultra-low quiescent current supports extended battery life in always-on portable and remote sensing applications.
Is the ADR520ARTZ-REEL7 RoHS compliant?
Yes, the ADR520ARTZ-REEL7 is RoHS compliant, as indicated by the "Z" suffix in its part number per Analog Devices' ordering guide. It meets EU Directive 2011/65/EU requirements and contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE).
