Product details
Overview
ADR5045ARTZ-REEL from Analog Devices is a precision 5.0 V shunt voltage reference in a 3-lead SOT-23 (RT-3) package, designed for high-accuracy analog signal conditioning and data acquisition. It delivers ±0.1% initial accuracy, 75 ppm/°C max temperature coefficient, and operates over −40°C to +125°C - enabling use in automotive power supplies and portable instrumentation.
For engineers reviewing the ADR5045ARTZ-REEL datasheet, ADR5045ARTZ-REEL pinout, ADR5045ARTZ-REEL application, or ADR5045ARTZ-REEL equivalent, key selection criteria include output stability under varying load current (50 µA–15 mA), low 6.6 µVrms (0.1–10 Hz) noise, fast 70 µs turn-on settling, and compatibility with capacitive loads without external compensation.
Technical Context
The ADR5045ARTZ-REEL implements a bandgap-based shunt architecture that generates a stable 5.0 V reference by summing complementary temperature coefficients - achieving near-zero net drift across −40°C to +125°C. Its dynamic output impedance remains at 0.2 Ω over the full operating current range, ensuring minimal voltage shift under transient load changes.
Unlike series references, it requires only an external bias resistor (RBIAS) to set operating current, supports stacking for higher or negative outputs, and maintains stability with any capacitive load - eliminating mandatory bypass capacitor design constraints while retaining 40 ppm output hysteresis performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V (Grade B, 100 µA test current; ±5 mV tolerance ensures ≤0.1% error in 12-bit ADC reference applications) |
| Initial Accuracy | ±0.1% (Grade B; guarantees absolute voltage error ≤±5 mV at 25°C, critical for calibration-critical systems) |
| Temp. Coefficient | 75 ppm/°C max (−40°C to +125°C; limits drift to ±0.375 mV over full range, supporting automotive-grade stability) |
| Operating Current | 50 µA to 15 mA (ultra-low minimum enables >10-year battery life in sensor nodes; 15 mA max supports high-speed DAC buffers) |
| Voltage Noise | 6.6 µVrms (0.1–10 Hz); 280 µVrms (10 Hz–10 kHz) - low flicker noise preserves SNR in precision measurement front-ends) |
| Turn-On Settling | 70 µs (CLOAD = 0 µF; enables rapid power-up in wake-on-event systems without reference stabilization delay) |
| Dynamic Impedance | 0.2 Ω (ensures <1 mV output shift for 5 mA load transients, suitable for driving op-amp inputs directly) |
Pinout & Package
ADR5045ARTZ-REEL uses the JEDEC-standard 3-lead SOT-23 (RT-3) package, measuring 2.90 mm × 1.30 mm × 1.02 mm, with gull-wing leads and 0.95 mm lead pitch. The package is RoHS-compliant and qualified for reflow per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Anode / Reference Output | Provides regulated 5.0 V output; must be connected to system VCC via external bias resistor (RBIAS) |
| V− | Cathode / Ground Reference | Return path for shunt current; connects to system ground or negative rail in inverted configurations |
| T | Trim / Temperature Sense | Internal trim node; datasheet recommends connection to V+ to ensure optimal accuracy and thermal stability |
Key Features
| Feature | Design Value |
|---|---|
| No external capacitor required | Stable with any capacitive load up to 10 µF - eliminates layout constraints and reduces BOM count in space-constrained designs |
| Precision grade-B accuracy | ±0.1% initial error (±5 mV) - meets requirements for 16-bit SAR ADC reference without trimming |
| Automotive-qualified variant available | ADR5045WARTZ-REEL7 shares same RT-3 footprint and electrical specs but includes AEC-Q100 stress testing and PPAP documentation |
| Wide operating current range | 50 µA min enables micro-power operation; 15 mA max supports driving multiple op-amps or ADC references simultaneously |
| Low 0.1–10 Hz noise | 6.6 µVrms - minimizes offset drift in high-gain instrumentation amplifiers used in weigh scales and medical sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR5045BRTZ-REEL7 | Identical electrical specs and RT-3 package; differs only in reel quantity (3,000 vs. 1,000) and tape-and-reel marking code (R32 vs. R30) | No functional difference; both support same automotive and industrial use cases | Select ADR5045ARTZ-REEL for standard volume procurement; choose ADR5045BRTZ-REEL7 only if specific reel size or traceability requirements apply |
| LM4040C50IDCKR | 5.0 V, ±0.5% initial accuracy, 100 ppm/°C TC, 60 µA–15 mA range; SOT-23-3 package but no T-pin | Lower accuracy and higher drift limit use to non-critical biasing or consumer-grade systems | Choose LM4040C50IDCKR only when cost sensitivity outweighs precision needs; not suitable for 16-bit+ data acquisition |
Compared with ADR5045ARTZ-REEL, ADR5045BRTZ-REEL7 offers identical performance in a functionally interchangeable package, while LM4040C50IDCKR trades 5× lower accuracy and 33% higher temperature drift for lower cost - making it viable only in non-calibrated, wide-tolerance applications.

FAQ
What is the maximum operating current for ADR5045ARTZ-REEL?
The ADR5045ARTZ-REEL supports a maximum operating current of 15 mA, as specified in its Absolute Maximum Ratings and confirmed across all electrical characteristics tables. This allows it to drive moderate-current loads such as op-amp inputs or multiple parallel reference paths without degradation in output voltage stability or accuracy.
Does ADR5045ARTZ-REEL require an external capacitor for stability?
No, the ADR5045ARTZ-REEL does not require an external capacitor for stability. Its internal design ensures unconditional stability with any capacitive load, including values up to 10 µF. This eliminates mandatory bypass capacitors and simplifies PCB layout in compact, battery-powered systems.
Is ADR5045ARTZ-REEL qualified for automotive applications?
The ADR5045ARTZ-REEL itself is not automotive-qualified; however, the pin-compatible ADR5045WARTZ-REEL7 variant is AEC-Q100 qualified and manufactured under automotive-specific process controls. Both share identical RT-3 packaging and electrical specifications except for qualification documentation and traceability.
What is the purpose of the T pin on ADR5045ARTZ-REEL?
The T pin on ADR5045ARTZ-REEL is an internal trim node. The datasheet explicitly recommends connecting it to V+ to ensure optimal initial accuracy and minimize thermal hysteresis. Leaving it unconnected may result in degraded performance, particularly in high-precision applications.
Can ADR5045ARTZ-REEL be used to generate a negative reference voltage?
Yes, ADR5045ARTZ-REEL can be configured as a precision negative reference by reversing its connection: connect V− to system ground and V+ to a negative supply rail, with appropriate biasing. Figure 20 in the datasheet shows this configuration using the ADR5045, confirming its suitability for −5 V reference generation.
