Product details
Overview
ADR363AUJZ-REEL7 from Analog Devices is a precision 3.000 V band gap voltage reference IC with sink/source capability, 25 ppm/°C temperature coefficient (A grade), ±6 mV initial accuracy, and ultralow 8.7 µVp-p (0.1 Hz to 10 Hz) output noise-designed for high-stability analog signal chains in portable medical instruments and battery-powered data acquisition systems.
For engineers reviewing the ADR363AUJZ-REEL7 datasheet, ADR363AUJZ-REEL7 pinout, ADR363AUJZ-REEL7 application, or ADR363AUJZ-REEL7 equivalent, this device delivers low dropout (300 mV), no external capacitor requirement, −40°C to +125°C operation, and 5 mA sourcing / −1 mA sinking capability in a compact 5-lead TSOT package.
Technical Context
The ADR363AUJZ-REEL7 implements a proprietary curvature-corrected band gap architecture where the reference is referenced to VOUT-not ground-enabling superior ground noise rejection. Its internal trim terminal allows fine adjustment of output voltage without external resistors.
It operates as a micropower, low-dropout voltage reference requiring only VIN ≥ VOUT + 300 mV, with quiescent current capped at 190 µA across −40°C to +125°C and no external stabilization capacitors needed for stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000 V ±6 mV (A grade, 25°C); enables direct interface with 3 V ADCs and DACs without scaling. |
| Tempco | 25 ppm/°C (−40°C to +125°C); ensures ≤ ±0.75 mV drift over full industrial temperature range. |
| Noise (0.1–10 Hz) | 8.7 µVp-p; supports 16-bit+ precision measurements in low-frequency sensor front-ends. |
| Dropout Voltage | 300 mV; allows operation from 3.3 V rails with ≥300 mV headroom-critical for Li-ion battery discharge profiles. |
| Quiescent Current | 190 µA max; enables >1-year battery life in 10 µA sleep-mode portable systems. |
| Output Drive | +5 mA sourcing / −1 mA sinking; drives ADC reference inputs, op-amp bias networks, and small DAC loads directly. |
| Long-Term Stability | 50 ppm (1000 hrs); guarantees minimal calibration drift in field-deployed instrumentation. |
Pinout & Package
ADR363AUJZ-REEL7 is housed in a 5-lead TSOT (UJ-5) package-0.9 mm × 2.1 mm footprint, 0.5 mm pitch-with exposed pad for thermal performance (θJA = 230°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NIC) | Not Internally Connected | No electrical function; must be left floating or grounded per PCB layout best practice-no routing required. |
| 2 (GND) | Ground Reference | Primary return path for reference core and output stage; requires low-impedance connection to system analog ground. |
| 3 (VIN) | Input Supply | Accepts 3.3 V to 15 V; minimum 300 mV above VOUT for regulation-supports wide-input battery and LDO-supplied rails. |
| 4 (VOUT) | Precision Output | Stable 3.000 V reference source; capable of sourcing 5 mA or sinking 1 mA while maintaining accuracy. |
| 5 (TRIM) | Voltage Adjustment | Allows ±0.5% output tuning via external resistor divider; enables calibration without changing BOM. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow 0.1–10 Hz noise | 8.7 µVp-p enables sub-16-bit noise floor in precision weigh scales and ECG front-ends. |
| No external capacitor required | Eliminates two passive components and associated board area-reducing BOM cost and layout complexity. |
| Ground-referenced band gap topology | Rejects ground bounce and digital noise coupling into VOUT-critical for mixed-signal SoC interfaces. |
| Trim terminal with laser-trimmed accuracy | ±6 mV initial error (A grade) plus adjustable output allows factory calibration without custom variants. |
| Wide operating temperature range | −40°C to +125°C rating supports under-hood automotive sensors and industrial PLC modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3430ARJZ-R7 | Same 3.0 V output, but lower 10 ppm/°C tempco (B grade), ±2 mV accuracy, and higher 300 µA IQ. | Better stability for lab-grade instruments; less suitable for ultra-low-power battery designs. | Select when long-term drift and temperature stability outweigh quiescent current constraints. |
| REF3330AIDBVR | 3.0 V output, 10 ppm/°C tempco, ±0.2% initial accuracy, 4 µVp-p noise-but only 5 mA sourcing, no sinking capability. | Limited to unidirectional load applications; lacks TRIM pin for post-assembly calibration. | Choose for lowest noise in sourcing-only applications where trimming and sinking are unnecessary. |
Compared with ADR363AUJZ-REEL7, ADR3430ARJZ-R7 offers tighter tempco at higher supply current, while REF3330AIDBVR provides lower noise but sacrifices sinking capability and adjustability-making ADR363AUJZ-REEL7 optimal for bidirectional, field-calibratable, low-power industrial references.

FAQ
What is the maximum input voltage for ADR363AUJZ-REEL7?
The absolute maximum supply voltage for ADR363AUJZ-REEL7 is 18 V, as specified in the Absolute Maximum Ratings table. Continuous operation above 15 V is limited to ≤10 seconds during short-circuit events; normal operation should remain within 3.3 V to 15 V to ensure reliability and maintain specified electrical characteristics across temperature.
Does ADR363AUJZ-REEL7 require an output capacitor?
No, ADR363AUJZ-REEL7 does not require an external output capacitor for stability-the internal design eliminates this need. Adding one may degrade transient response or cause oscillation. The datasheet explicitly states "no external capacitor required" and validates stability with zero output capacitance in all transient and noise test conditions.
Can ADR363AUJZ-REEL7 sink current, and how much?
Yes, ADR363AUJZ-REEL7 can actively sink up to −1 mA while maintaining output accuracy and regulation. This bidirectional capability supports applications like active biasing of op-amp inputs, programmable current sources, and dynamic load compensation-distinct from unidirectional references such as REF3330.
What is the purpose of the TRIM pin on ADR363AUJZ-REEL7?
The TRIM pin (Pin 5) on ADR363AUJZ-REEL7 enables fine adjustment of the output voltage using an external resistor divider. It supports ±0.5% tuning around the nominal 3.000 V, allowing system-level calibration without redesigning the reference circuit or selecting custom voltage variants.
Is ADR363AUJZ-REEL7 qualified for automotive use?
ADR363AUJZ-REEL7 is rated for −40°C to +125°C operation and meets industrial reliability standards, but it is not AEC-Q100 qualified. For automotive applications, Analog Devices offers the ADR365WHUJZ-R7 (H grade, −40°C to +150°C) or ADR363BH variant-neither of which applies to the ADR363AUJZ-REEL7 part number.
