Product details
Overview
ADR5044ARTZ-REEL from Analog Devices is a precision 4.096 V shunt voltage reference in a 3-lead SOT-23 (RT-3) package, delivering ±0.1% initial accuracy, 75 ppm/°C max temperature coefficient, and stable operation from 50 µA to 15 mA over −40°C to +125°C. It serves as a compact, low-power reference for high-resolution ADCs and DACs in portable instrumentation.
For engineers reviewing the ADR5044ARTZ-REEL datasheet, ADR5044ARTZ-REEL pinout, ADR5044ARTZ-REEL application, or ADR5044ARTZ-REEL equivalent, key selection criteria include output voltage tolerance, thermal drift in extended temperature environments, minimum operating current for battery-constrained designs, and compatibility with capacitive loads without external compensation.
Technical Context
The ADR5044ARTZ-REEL implements a bandgap-based shunt architecture that cancels intrinsic semiconductor temperature dependence via curvature-compensated circuitry. Its output remains stable across input current variations (50 µA–15 mA) and load capacitance (0–1 µF), eliminating need for external bypass capacitors.
It operates as a two-terminal device requiring only an external bias resistor, with reverse-biased configuration enabling use in both positive and negative reference topologies. The device exhibits 40 ppm hysteresis and 56 µs turn-on settling time at zero load capacitance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLVH431ACDBVR | 2.5 V fixed output; ±0.5% initial accuracy; 100 ppm/°C tempco; requires external resistor for adjustable mode. | Lower precision and higher drift limit use in non-critical biasing or marginally specified power supplies. | Select when cost sensitivity outweighs 4.096 V matching and ±0.1% accuracy requirements. |
| REF3040AIDBZR | 4.096 V output; ±0.2% initial accuracy; 100 ppm/°C tempco; 50 µA–25 mA operating range; SOT-23-3 package. | Higher initial error and drift reduce usable resolution in 12-bit+ systems; wider current range suits higher-load applications. | Choose when broader current capability is needed and ±0.2% tolerance is acceptable for system-level calibration. |
Compared with TLVH431ACDBVR and REF3040AIDBZR, the ADR5044ARTZ-REEL provides superior initial accuracy and lower temperature drift-critical for uncalibrated 12-bit data converters-while maintaining identical SOT-23-3 footprint and biasing simplicity.

FAQ
What is the output voltage tolerance of the ADR5044ARTZ-REEL at room temperature?
The ADR5044ARTZ-REEL has a nominal output voltage of 4.096 V with ±0.1% initial accuracy at 25°C, corresponding to a tolerance band of 4.092 V to 4.100 V when tested at 100 µA operating current. This specification is guaranteed for Grade B devices and is verified during production test per Analog Devices' Rev. E datasheet.
Does the ADR5044ARTZ-REEL require an external capacitor for stability?
No, the ADR5044ARTZ-REEL does not require an external capacitor for stability. Its internal design ensures unconditional stability with any capacitive load from 0 µF to 1 µF, as confirmed in the Applications Information section of the datasheet. This eliminates layout constraints and reduces bill-of-materials count.
Can the ADR5044ARTZ-REEL be used in negative reference configurations?
Yes, the ADR5044ARTZ-REEL can be configured as a precision negative reference by reversing its connection-placing the V− terminal at system ground and sourcing current into the V+ terminal. Figure 20 in the datasheet illustrates this topology, enabling −4.096 V generation with appropriate biasing and low-TC resistors.
What is the minimum operating current for the ADR5044ARTZ-REEL across temperature?
The ADR5044ARTZ-REEL requires a minimum operating current of 60 µA across the full −40°C to +125°C temperature range, increasing from 50 µA at 25°C. This ensures proper bandgap core activation and regulation stability under worst-case thermal conditions.
Is the ADR5044ARTZ-REEL pin-compatible with other references in its family?
Yes, the ADR5044ARTZ-REEL shares identical 3-lead SOT-23 (RT-3) pinout and biasing requirements with all ADR504x variants-including ADR5040, ADR5041, ADR5043, and ADR5045-enabling drop-in replacement within the same voltage grade (e.g., ADR5044BRTZ-REEL) without PCB modification.
