Product details
Overview
ADR5040ARTZ-REEL from Analog Devices is a precision 2.048 V shunt voltage reference in a 3-lead SOT-23 (RT-3) package, designed for space-constrained, battery-powered systems requiring stable reference voltage with ±0.1% initial accuracy, 75 ppm/°C max temperature coefficient, and operation from −40°C to +125°C. It delivers low 2.8 µVrms (0.1–10 Hz) noise and 28 µs turn-on settling time, enabling high-resolution ADC biasing in portable instrumentation.
For engineers reviewing the ADR5040ARTZ-REEL datasheet, ADR5040ARTZ-REEL pinout, ADR5040ARTZ-REEL application, or ADR5040ARTZ-REEL equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed automotive-grade alternatives - all grounded in Analog Devices' Rev. E datasheet and ordering guide.
Technical Context
The ADR5040ARTZ-REEL implements a bandgap-based shunt architecture that generates a stable 2.048 V output without external compensation capacitors, maintaining stability across any capacitive load. Its design eliminates need for trimming or external components while supporting wide operating current (50 µA to 15 mA) and extended temperature range (−40°C to +125°C).
It features ultralow dynamic output impedance (0.2 Ω), 40 ppm output voltage hysteresis, and guaranteed 75 ppm/°C max temperature coefficient over full temperature range - critical for data acquisition systems where thermal drift directly impacts measurement fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048 V ±0.1% (±2.048 mV) at 100 µA - enables precise 12-bit DAC/ADC scaling with minimal calibration overhead |
| Temp Coefficient | ≤75 ppm/°C (−40°C to +125°C) - ensures ≤155 µV total drift over full range, suitable for automotive sensor signal chains |
| Operating Current | 50 µA to 15 mA - supports ultra-low-power sleep modes and high-speed wake-up without re-stabilization delay |

| Settling Time | 28 µs (CLOAD = 0 µF) - allows rapid reference enable/disable in duty-cycled measurement systems |
| Package | 3-lead SOT-23 (RT-3), 2.90 mm × 1.30 mm footprint - fits high-density PCB layouts in handheld medical devices |
Pinout & Package
ADR5040ARTZ-REEL uses the RT-SOT-23-3 (RT-3) package per JEDEC TO-236-AB, with 1.02 mm height and 0.65 mm lead pitch. Pin 3 must be connected to V+ per datasheet recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V+) | Anode / Reference Output Terminal | Provides regulated 2.048 V output; connects to load and bias resistor; requires external RBIAS for current sourcing |
| 2 (V−) | Cathode / Ground Reference Terminal | Serves as return path for shunt current; ties to system ground or negative rail in inverted configurations |
| 3 (T) | Thermal Pad / Optional V+ Tie | Recommended connection to V+ to improve thermal stability and reduce hysteresis; not electrically isolated |
Key Features
| Feature | Design Value |
|---|---|
| No external capacitor required | Stable with any capacitive load up to 1 µF - eliminates BOM cost and layout risk of decoupling capacitor selection |
| Precision grade B accuracy | ±0.1% initial error (±2.048 mV) - reduces or eliminates factory calibration steps in production test |
| Automotive-qualified variant available | ADR5040WARTZ-R7 meets AEC-Q200 requirements - supports direct use in engine control and ADAS modules |
| Wide current range | 50 µA minimum operating current - enables operation from coin-cell batteries (e.g., CR2032) for >10-year shelf life |
| SC70/SOT-23 pin compatibility | Pins 1–2–3 match LM4040/LM4050 footprints - allows drop-in replacement in legacy designs without PCB revision |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040C20IDBZR | 2.048 V, ±0.5% initial accuracy, 100 ppm/°C TC, 60 µA min current - looser tolerance and higher drift than ADR5040ARTZ-REEL | Cost-sensitive industrial controls where ±0.5% accuracy suffices; not qualified for automotive | Select when BOM cost priority outweighs precision and temperature stability requirements |
| ADR5040BRTZ-REEL7 | Identical electrical specs and RT-3 package; differs only in reel quantity (3,000 vs. 7,000) and marking code (R2L vs. R2L) | No functional difference; same automotive qualification status and performance | Choose based on volume procurement needs and distributor inventory alignment |
Compared with LM4040C20IDBZR, ADR5040ARTZ-REEL delivers 5× tighter initial accuracy and 30% lower temperature drift, making it essential for metrology-grade systems; versus ADR5040BRTZ-REEL7, it is functionally identical but optimized for different packaging logistics.

FAQ
What is the output voltage tolerance of ADR5040ARTZ-REEL at 25°C?
The ADR5040ARTZ-REEL has a guaranteed initial accuracy of ±0.1% at 100 µA operating current and 25°C, corresponding to ±2.048 mV around its nominal 2.048 V output. This Grade B specification is explicitly defined in Table 2 of the Rev. E datasheet and applies across the full −40°C to +125°C temperature range when combined with its 75 ppm/°C max temperature coefficient.
Does ADR5040ARTZ-REEL require an external capacitor for stability?
No, the ADR5040ARTZ-REEL does not require an external capacitor for stability. Its internal design ensures unconditional stability with any capacitive load, including 0 µF to 1 µF, as confirmed in the General Description and Applications Information sections of the datasheet. This eliminates layout dependencies and reduces bill-of-materials count.
What is the minimum operating current for ADR5040ARTZ-REEL over temperature?
The ADR5040ARTZ-REEL requires a minimum operating current of 60 µA across the full −40°C to +125°C temperature range, per Table 2's "MINIMUM OPERATING CURRENT" row. At 25°C, the minimum is 50 µA. This defines the lower bound for bias resistor sizing in shunt reference circuits.
Is ADR5040ARTZ-REEL qualified for automotive applications?
The ADR5040ARTZ-REEL itself is not automotive-qualified; however, the pin-compatible ADR5040WARTZ-R7 variant is AEC-Q200 qualified and manufactured under controlled automotive processes. Both share identical electrical specifications and RT-3 packaging, but only the "W" suffix denotes automotive qualification per the Ordering Guide and Automotive Products section.
How does the T pin (Pin 3) function in ADR5040ARTZ-REEL?
Pin 3 (T) on the ADR5040ARTZ-REEL is a thermal pad recommended for connection to V+ to improve thermal stability and reduce output voltage hysteresis. It is not electrically isolated and serves a mechanical/thermal role - not a signal or control function - as specified in the Pin Configuration note and Figure 1 of the datasheet.
