Product details
Overview
ADR365WAUJZ-RL from Analog Devices is a precision 5.000 V band gap voltage reference with A-grade accuracy (±8 mV), 25 ppm/°C temperature coefficient, and sink/source capability (±1 mA/5 mA) in a 5-lead TSOT package. It operates from −40°C to +125°C with 300 mV dropout and 12.8 µVp-p (0.1 Hz–10 Hz) output noise, serving as a stable reference for high-resolution ADCs and DACs in portable instrumentation.
For engineers reviewing the ADR365WAUJZ-RL datasheet, ADR365WAUJZ-RL pinout, ADR365WAUJZ-RL application, or ADR365WAUJZ-RL equivalent, this page delivers verified specifications, validated pin functions, confirmed automotive-grade thermal performance, and real-world load/line regulation behavior under industrial temperature extremes.
Technical Context
The ADR365WAUJZ-RL uses a proprietary curvature-corrected band gap architecture where the reference is referenced to VOUT-not ground-enabling inherent ground-noise rejection. Its internal trimming adjusts output voltage and temperature drift across the full −40°C to +125°C range.
It achieves low dropout (300 mV) via micropower design and eliminates external capacitors through internal stability compensation. Load regulation is specified at 0.9 mV/mA (sourcing) and 2.0 mV/mA (sinking) over temperature, with line regulation of 0.25 mV/V (−40°C to +125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±8 mV (A grade, 25°C); enables direct interface with 5 V ADC reference inputs without scaling. |
| Temp Coefficient | 25 ppm/°C (−40°C to +125°C); ensures ≤1.25 mV total drift over full industrial range. |
| Noise (0.1–10 Hz) | 12.8 µVp-p; supports 16-bit+ data acquisition systems without added filtering. |
| Dropout Voltage | 300 mV; allows operation from 5.3 V supply, minimizing power loss in battery-powered systems. |
| Quiescent Current | 190 µA max; extends battery life in portable medical instruments and handheld meters. |
| Output Current | +5 mA sourcing / −1 mA sinking; drives ADC reference inputs and small bias networks directly. |
| Long-Term Stability | 50 ppm (1000 hrs); reduces calibration frequency in field-deployed process control sensors. |
Pinout & Package
ADR365WAUJZ-RL is housed in a compact 5-lead TSOT (UJ-5) package with 0.65 mm pitch, optimized for space-constrained PCB layouts and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NIC | Not Internally Connected - must be left floating or tied to GND per layout best practice; no electrical function. |
| 2 | GND | Ground reference for internal band gap core and output stage; requires low-impedance connection to system ground plane. |
| 3 | VIN | Input supply connection; minimum headroom = VOUT + 300 mV; accepts up to 15 V input. |
| 4 | VOUT | Stable 5.000 V reference output; capable of sourcing 5 mA or sinking 1 mA into load. |
| 5 | TRIM | Output voltage trim terminal; used with external resistor network to adjust VOUT by ±0.5% (per datasheet Figure 38). |
Key Features
| Feature | Design Value |
|---|---|
| No external capacitor required | Eliminates 1–2 external 1 µF ceramics, reducing BOM count and board area in portable designs. |
| Ground-referenced band gap topology | Attenuates ground-plane noise coupling into VOUT, improving SNR in mixed-signal sensor front-ends. |
| Sink/source capability | Directly biases op-amp references, current sources, or DAC reference inputs without external buffers. |
| Automotive-qualified operating range | Validated for −40°C to +125°C operation, meeting AEC-Q100 stress test requirements for engine control modules. |
| Laser-trimmed initial accuracy | ±8 mV (±0.16%) at 25°C ensures first-pass calibration success in production test fixtures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR365BUJZ-REEL7 | Same 5.000 V output but B-grade (±4 mV, 9 ppm/°C); lower initial error and drift. | Better suited for high-accuracy data loggers requiring <10 ppm total error budget. | Select if tighter initial accuracy and temperature stability outweigh cost premium. |
| REF5050AIDR | 5.000 V, 3 ppm/°C, ±0.05% initial accuracy; higher quiescent current (950 µA) and SOIC-8 package. | Targeted at lab-grade instrumentation where ultra-low drift dominates power/space constraints. | Choose when sub-ppm/°C drift is mandatory and board space allows SOIC-8 footprint. |
Compared with ADR365WAUJZ-RL, the ADR365BUJZ-REEL7 offers superior drift performance at identical form factor and power, while REF5050AIDR trades 5× higher supply current and larger package for 3× lower temperature coefficient-making each optimal for distinct accuracy vs. power trade-offs.

FAQ
What is the maximum input voltage rating for ADR365WAUJZ-RL?
The absolute maximum supply voltage for ADR365WAUJZ-RL is 18 V, per the Absolute Maximum Ratings table. Continuous operation above 15 V is not recommended; for VIN > 15 V, short-circuit duration to GND is limited to 10 seconds. The device is rated for normal operation from 5.3 V to 15 V, ensuring safe margin across industrial and automotive rails.
Can ADR365WAUJZ-RL drive a 10 kΩ load at full temperature range?
Yes. With a 5.000 V output and ±8 mV initial accuracy, ADR365WAUJZ-RL delivers 0.5 mA into a 10 kΩ load-well within its +5 mA sourcing capability. Load regulation is specified at 0.9 mV/mA (−40°C to +125°C), so worst-case error remains under 0.45 mV, preserving reference integrity for 12-bit systems.
Is the TRIM pin on ADR365WAUJZ-RL required for standard operation?
No. The TRIM pin on ADR365WAUJZ-RL is optional and used only when fine adjustment of VOUT beyond factory calibration is needed-typically ±0.5% via external resistor divider. In standard applications, TRIM may be left unconnected or tied to GND; it does not affect baseline functionality or stability.
Does ADR365WAUJZ-RL require an input or output capacitor?
No. ADR365WAUJZ-RL is internally compensated and explicitly designed to operate stably without external input or output capacitors, as confirmed in the General Description and Applications Information sections. This eliminates capacitor-related aging, microphonics, and board space-critical for portable and high-reliability systems.
What is the thermal resistance (θJA) of ADR365WAUJZ-RL in its UJ-5 package?
The junction-to-ambient thermal resistance (θJA) for ADR365WAUJZ-RL in the 5-lead TSOT (UJ-5) package is 230°C/W, measured under natural convection in a one-cubic-foot sealed enclosure. This value assumes standard PCB copper pour; actual θJA improves significantly with enhanced thermal land design and airflow.
