Product details
Overview
ADR5043ARTZ-REEL from Analog Devices is a precision 3.0 V shunt voltage reference in SOT-23-3 package, delivering ±0.1% initial accuracy, 75 ppm/°C max temperature coefficient, and stable operation from 50 µA to 15 mA supply current across −40°C to +125°C. It serves as a compact, low-power reference for high-resolution ADCs and battery-powered instrumentation.
For engineers reviewing the ADR5043ARTZ-REEL datasheet, ADR5043ARTZ-REEL pinout, ADR5043ARTZ-REEL application, or ADR5043ARTZ-REEL equivalent, key selection criteria include output voltage tolerance, thermal drift performance, minimum operating current, load regulation behavior, and compatibility with capacitive loads without external compensation.
Technical Context
The ADR5043ARTZ-REEL implements a band gap–based shunt architecture that generates a stable 3.0 V reference by summing complementary temperature coefficients to achieve near-zero net drift. Its design eliminates need for external stabilization capacitors while maintaining stability under any capacitive load condition.
It operates as a two-terminal device requiring only an external bias resistor to set operating current; its dynamic output impedance remains at 0.2 Ω across 50 µA–15 mA, enabling fast settling (42 µs) and low hysteresis (40 ppm). The device is characterized over full automotive temperature range and supports stacking for higher or negative reference voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000 V ±3 mV at 100 µA - ensures ≤0.1% absolute error in precision data acquisition scaling |
| Initial Accuracy | ±0.1% - guarantees maximum 3 mV deviation at 25°C before calibration |
| Temp. Coefficient | ≤75 ppm/°C - limits worst-case drift to ±9.0 mV over −40°C to +125°C |
| Operating Current | 50 µA to 15 mA - enables ultra-low-power sensor nodes and high-current DAC references |
| Settling Time | 42 µs (CLOAD = 0 µF) - supports rapid power-up in portable systems with wake-on-event logic |
| Voltage Noise | 4.3 µV rms (0.1–10 Hz), 180 µV rms (10 Hz–10 kHz) - preserves ENOB in 16-bit+ ADC front-ends |
| Dynamic Impedance | 0.2 Ω - minimizes load-induced output shift during transient current demand |
Pinout & Package
ADR5043ARTZ-REEL uses the 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB, with 1.30 mm × 2.10 mm footprint and 0.95 mm height. Pin 3 must be connected to V+ per datasheet recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Anode / Input Terminal | Connects to bias resistor; carries total current (IIN = ILOAD + IREF) |
| V− | Cathode / Output Terminal | Provides regulated 3.0 V reference node; referenced to system ground |
| T | Trim / Temperature Sense | Internally tied to bandgap core; externally connected to V+ to stabilize thermal response |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040C30IDBZR | ±0.5% initial accuracy, 100 ppm/°C TC, 60 µA min current | Lower precision; suited for cost-sensitive consumer electronics, not metrology | Select when budget constraints outweigh accuracy requirements and temperature range is limited to 0°C–70°C |
| ADR3430ARJZ-R7 | 3.0 V series reference, ±0.1% accuracy, 50 ppm/°C TC, 100 µA quiescent current | Three-terminal architecture requires separate ground; less flexible biasing than shunt topology | Choose for fixed-supply systems where load regulation and PSRR are prioritized over layout simplicity |
Compared with LM4040C30IDBZR and ADR3430ARJZ-R7, the ADR5043ARTZ-REEL offers superior thermal stability and lower minimum operating current, making it optimal for wide-temperature, battery-constrained, or space-limited applications where shunt topology simplifies design.

FAQ
What is the maximum operating current for ADR5043ARTZ-REEL?
The ADR5043ARTZ-REEL supports up to 15 mA of input current, which defines its upper operating limit for stable regulation. Exceeding this value risks exceeding absolute maximum ratings and may cause irreversible damage or parametric shift. This 15 mA ceiling allows robust operation in high-load scenarios such as driving multiple op-amp reference inputs or powering auxiliary circuitry directly from the reference node.
Does ADR5043ARTZ-REEL require an external capacitor for stability?
No, the ADR5043ARTZ-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. This eliminates layout sensitivity and reduces bill-of-materials count-unlike many older shunt references that mandate specific capacitor values and placement to prevent oscillation.
Can ADR5043ARTZ-REEL be used in automotive applications?
The standard ADR5043ARTZ-REEL is rated for −40°C to +125°C and qualified for industrial use, but it is not AEC-Q100 certified. For automotive applications, Analog Devices offers the ADR5043WARTZ-R7 variant, which undergoes controlled manufacturing and additional reliability testing per automotive standards. Use ADR5043WARTZ-R7-not ADR5043ARTZ-REEL-for safety-critical or under-hood deployments.
How is the minimum bias resistor calculated for ADR5043ARTZ-REEL?
The minimum bias resistor RBIAS is calculated using RBIAS = (VS − VOUT) / (IIN(MIN) + IL(MAX)), where VS is minimum supply voltage, VOUT = 3.0 V, IIN(MIN) = 60 µA (over temperature), and IL(MAX) is maximum load current. This ensures sufficient current flows through ADR5043ARTZ-REEL even under worst-case voltage and load conditions.
Is ADR5043ARTZ-REEL pin-compatible with LM4040 series devices?
Yes, ADR5043ARTZ-REEL is explicitly designed as pin-compatible with LM4040 and LM4050 shunt references in SOT-23-3 package. It shares identical pinout (V+, V−, T), footprint, and biasing methodology-enabling direct replacement without PCB modification. However, ADR5043ARTZ-REEL delivers tighter initial accuracy (±0.1% vs. ±0.5%) and lower temperature coefficient (75 ppm/°C vs. 100 ppm/°C).
