Product details
Overview
ADR364BUJZ-REEL7 from Analog Devices is a precision 4.096 V band gap voltage reference IC with sink/source capability, 9 ppm/°C temperature coefficient (B grade), ±4 mV initial accuracy, and ultralow 11 µVp-p (0.1 Hz to 10 Hz) output noise-designed for high-resolution data acquisition systems requiring stable excitation in portable medical instruments.
For engineers reviewing the ADR364BUJZ-REEL7 datasheet, ADR364BUJZ-REEL7 pinout, ADR364BUJZ-REEL7 application, or ADR364BUJZ-REEL7 equivalent, this device delivers low dropout (300 mV), no external capacitor requirement, and operation across −40°C to +125°C-critical for battery-powered instrumentation where power efficiency and thermal stability are non-negotiable.
Technical Context
The ADR364BUJZ-REEL7 uses proprietary temperature drift curvature correction to achieve 9 ppm/°C TC over −40°C to +125°C while maintaining 4.096 V nominal output. Its band gap architecture references the output-not ground-providing inherent ground-noise rejection.
It operates with a minimum input headroom of 300 mV above VOUT, supports ±1 mA sinking / +5 mA sourcing, and achieves 25 µs turn-on settling without external capacitors-enabling compact, low-BOM-count designs in space-constrained applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096 V nominal; tight tolerance (±4 mV max) enables direct interface with 12-bit ADCs without calibration. |
| Temp Coefficient | 9 ppm/°C (B grade); ensures ≤ ±0.45 mV drift over −40°C to +125°C-suitable for industrial process control. |
| Voltage Noise | 11 µVp-p (0.1 Hz–10 Hz); low enough to avoid degrading ENOB in 16-bit SAR ADC front-ends. |
| Dropout Voltage | 300 mV; allows operation from single-cell Li-ion (3.0 V min) or 5 V rails with minimal headroom loss. |
| Quiescent Current | 190 µA max; enables multi-year battery life in portable medical sensors and handheld meters. |
| Load Regulation | 0.735 mV/mA (sourcing); predictable output shift under dynamic load simplifies system-level error budgeting. |
| Long-Term Stability | 50 ppm (1000 hrs); low aging drift reduces recalibration frequency in field-deployed instrumentation. |
Pinout & Package
ADR364BUJZ-REEL7 is housed in a 5-lead TSOT (UJ-5) package with exposed pad for thermal enhancement. The package measures 2.1 mm × 1.6 mm × 0.55 mm (max height) and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NIC) | Not Internally Connected | No internal bond; must be left floating or tied to GND per layout best practice-no electrical function. |
| 2 (GND) | Ground Reference | Primary return path; requires low-impedance connection to system ground plane to minimize noise coupling. |
| 3 (VIN) | Input Supply | Accepts 4.4 V to 15 V; minimum 300 mV headroom above VOUT required for regulation. |
| 4 (VOUT) | Reference Output | Stable 4.096 V source; capable of sourcing up to 5 mA or sinking up to 1 mA into load. |
| 5 (TRIM) | Output Voltage Adjustment | Allows fine-tuning via external resistor divider; typical trim range ±0.5% around nominal VOUT. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow noise output | 11 µVp-p (0.1 Hz–10 Hz) directly supports high-precision analog signal chains without post-filtering. |
| No external capacitor needed | Eliminates two passive components and associated board area-reducing BOM cost and layout complexity. |
| Sink/source capability | ±1 mA sinking / +5 mA sourcing enables active biasing of transducers and driving of ADC reference inputs. |
| Low dropout operation | 300 mV headroom allows use with low-voltage supplies (e.g., 4.4 V min), extending battery runtime. |
| Automotive-qualified option | H-grade variants (e.g., ADR364HUJZ-R7) support −40°C to +150°C operation-this B-grade part is industrial-rated. |
Applications
| Battery-Powered Instruments | Portable Medical Instruments |
|---|---|
|
Use Scenario: Handheld multimeters and portable DMMs powered by AA/AAA batteries. IC Role / Device Role / Timing Role: Precision voltage reference for ADC excitation and internal calibration.

| Data Acquisition Systems | Industrial Process Controls |
|
Use Scenario: 16-bit isolated DAQ modules for sensor signal conditioning in factory automation. IC Role / Device Role / Timing Role: Primary reference for SAR ADCs and DACs in measurement subsystems. Use Value: Low long-term stability (50 ppm/1000 hrs) minimizes recalibration intervals in unattended deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3440BRMZ-REEL | 4.096 V, 10 ppm/°C TC, 12 µVp-p noise, 200 µA IQ, same UJ-5 package. | Higher noise and looser TC; lacks TRIM pin-no output adjustment capability. | Select when TRIM functionality is unnecessary and cost sensitivity outweighs 1 ppm/°C TC advantage. |
| REF5040AIDR | 4.096 V, 3 ppm/°C TC, 5 µVp-p noise, 950 µA IQ, SOIC-8 package. | Lower noise and superior TC-but 5× higher quiescent current and larger footprint. | Select for ultra-high-precision lab equipment where power and size are secondary to stability. |
Compared with ADR364BUJZ-REEL7, ADR3440BRMZ-REEL trades TRIM capability and tighter TC for lower cost, while REF5040AIDR offers significantly better noise and TC at the expense of power and board space-making ADR364BUJZ-REEL7 optimal for portable, battery-sensitive, and trim-enabled applications.

FAQ
What is the operating temperature range for ADR364BUJZ-REEL7?
The ADR364BUJZ-REEL7 is rated for operation from −40°C to +125°C. This industrial-grade temperature range is validated per the ADR364 B-grade specifications in the Rev. E datasheet and applies across all electrical parameters including initial accuracy, temperature coefficient, and load regulation.
Does ADR364BUJZ-REEL7 require an external output capacitor?
No, ADR364BUJZ-REEL7 does not require an external output capacitor for stability. Its internal compensation and architecture eliminate the need for external capacitance-reducing bill-of-materials count and PCB area while maintaining 25 µs turn-on settling time and robust load transient response.
What is the purpose of the TRIM pin on ADR364BUJZ-REEL7?
The TRIM pin (Pin 5) on ADR364BUJZ-REEL7 allows fine adjustment of the output voltage using an external resistor divider. It supports bidirectional trimming within approximately ±0.5% of the nominal 4.096 V output, enabling system-level calibration without replacing the reference IC.
Can ADR364BUJZ-REEL7 sink current, and how much?
Yes, ADR364BUJZ-REEL7 can sink up to −1 mA of current from its VOUT pin. This sink capability supports active pull-down configurations-for example, biasing current sources or driving the reference input of certain ADCs that require controlled discharge paths during power-down sequences.
Is ADR364BUJZ-REEL7 qualified for automotive applications?
No, ADR364BUJZ-REEL7 is an industrial-grade (B grade) variant rated for −40°C to +125°C. For automotive use, Analog Devices offers the ADR364HUJZ-R7 (H grade), which is qualified to −40°C to +150°C and meets AEC-Q100 requirements-ADR364BUJZ-REEL7 itself is not automotive-qualified.
