Product details
Overview
ADR363BUJZ-REEL7 from Analog Devices is a precision 3.000 V band gap voltage reference IC with sink/source capability, 9 ppm/°C temperature coefficient (B grade), ±3 mV initial accuracy, and ultralow 8.7 µVp-p (0.1 Hz to 10 Hz) output noise. It operates from −40°C to +125°C with 300 mV dropout and 190 µA max quiescent current, enabling use in high-accuracy battery-powered data acquisition systems.
For engineers reviewing the ADR363BUJZ-REEL7 datasheet, ADR363BUJZ-REEL7 pinout, ADR363BUJZ-REEL7 application, or ADR363BUJZ-REEL7 equivalent, key selection criteria include output stability under load variation (0.54 mV/mA sourcing), low-noise performance for ADC reference rails, automotive-grade thermal range compatibility, and TSOT-5 package suitability for space-constrained PCB layouts.
Technical Context
The ADR363BUJZ-REEL7 implements a curvature-corrected band gap reference architecture where the reference node is referenced to VOUT-not ground-enabling inherent ground noise rejection. Its proprietary trimming and resistor ratio design achieves 9 ppm/°C drift over −40°C to +125°C without external capacitors.
It delivers bidirectional output current (±1 mA sinking / +5 mA sourcing) with 25 µs turn-on settling time and maintains regulation with input as low as VIN = VOUT + 300 mV. Load regulation is specified at 0.54 mV/mA (sourcing) and 1.2 mV/mA (sinking) across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000 V nominal; B-grade devices guaranteed 2.997 V to 3.003 V at 25°C - enables direct interface with 3 V ADCs and DACs without gain calibration. |
| Initial Accuracy | ±3 mV maximum (±0.1% of 3 V); reduces system-level offset error in precision sensor signal chains. |
| Temp. Coefficient | 9 ppm/°C (B grade, −40°C to +125°C); supports stable 16-bit+ measurement accuracy across industrial temperature range. |
| Output Noise | 8.7 µVp-p (0.1 Hz to 10 Hz); low enough to avoid limiting ENOB in 24-bit delta-sigma ADCs. |
| Dropout Voltage | 300 mV; allows operation from single-cell Li-ion (3.0 V min) or 3.3 V rail with margin for supply sag. |
| Quiescent Current | 190 µA maximum; enables multi-year battery life in portable medical instruments with intermittent sampling. |
| Sink/Source Current | +5 mA sourcing / −1 mA sinking; supports driving ADC reference inputs and small bias networks without external buffers. |
Pinout & Package
ADR363BUJZ-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 and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NIC) | Not Internally Connected | No internal connection; must be left floating or tied to GND per layout best practice - no electrical function. |
| 2 (GND) | Ground Reference | Primary return path for reference output and internal circuitry; requires low-impedance connection to system ground plane. |
| 3 (VIN) | Input Supply | Accepts 3.3 V to 15 V input; minimum headroom is 300 mV above VOUT - enables low-voltage operation with minimal overhead. |
| 4 (VOUT) | Precision Output | Stable 3.000 V reference output; capable of sourcing up to 5 mA or sinking up to 1 mA while maintaining regulation. |
| 5 (TRIM) | Voltage Trim Terminal | Allows fine adjustment of output via external resistor divider; typical trim range ±0.5% - used for system-level calibration. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow 0.1–10 Hz noise | 8.7 µVp-p - preserves dynamic range in high-resolution data acquisition systems with slow-sampling sensors. |
| No external capacitor required | Stable operation without input/output bypass caps - reduces BOM count, board area, and cost in compact designs. |
| Low dropout (300 mV) | Enables direct regulation from low-headroom supplies like coin cells or partially discharged batteries. |
| Bidirectional output drive | ±1 mA sink / +5 mA source - eliminates need for external op-amp buffers when driving reference inputs or bias networks. |
| Automotive-qualified thermal range | −40°C to +125°C operation (B grade) - meets AEC-Q100 stress test requirements for under-hood applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3430ARMZ-R7 | 3.0 V output, 3 ppm/°C (A grade), ±1.5 mV accuracy, but higher 220 µA IQ and requires 1 µF output cap. | Better drift spec but less suitable for ultra-low-power or capacitor-free designs. | Select ADR3430ARMZ-R7 only if sub-3 ppm/°C drift is mandatory and board space allows output capacitor. |
| REF3330AIDBZR | 3.0 V output, 10 ppm/°C (A grade), ±5 mV accuracy, 4 µVp-p noise, but limited to −40°C to +125°C and no sinking capability. | Lower noise but lacks sink current - unsuitable for circuits requiring reference current return paths. | Choose REF3330AIDBZR only for noise-critical, sourcing-only applications where ±5 mV initial error is acceptable. |
Compared with ADR363BUJZ-REEL7, ADR3430ARMZ-R7 offers superior temperature stability but increases power and layout complexity, while REF3330AIDBZR trades sink capability and accuracy for lower noise - making ADR363BUJZ-REEL7 the optimal balance for robust, low-power, bidirectional reference needs.

FAQ
What is the guaranteed output voltage tolerance for ADR363BUJZ-REEL7 at 25°C?
The ADR363BUJZ-REEL7 is a B-grade device with guaranteed output voltage of 2.997 V to 3.003 V at 25°C, corresponding to ±3 mV absolute error or ±0.1% of nominal 3.000 V. This specification is tested and binned during production and applies across the full operating temperature range of −40°C to +125°C.
Does ADR363BUJZ-REEL7 require external capacitors for stability?
No, ADR363BUJZ-REEL7 does not require external input or output capacitors for stability. Its internal compensation and advanced band gap architecture ensure unconditional stability across all load and line conditions within datasheet limits. Adding capacitors may degrade transient response or cause oscillation.
Can ADR363BUJZ-REEL7 sink current, and what is the maximum rated sink current?
Yes, ADR363BUJZ-REEL7 supports bidirectional output current. It can sink up to −1 mA while maintaining regulation and specified accuracy. This capability enables direct interfacing with circuits requiring reference current return paths, such as certain DAC configurations or bias networks.
What is the maximum allowable input voltage for ADR363BUJZ-REEL7?
The absolute maximum input voltage for ADR363BUJZ-REEL7 is 18 V, as specified in the Absolute Maximum Ratings table. However, for reliable continuous operation, VIN must remain within 3.3 V to 15 V per the Electrical Characteristics tables - exceeding 15 V risks permanent damage even for short durations.
Is ADR363BUJZ-REEL7 qualified for automotive applications?
ADR363BUJZ-REEL7 is rated for −40°C to +125°C operation and meets the thermal and reliability requirements for many automotive subsystems. While it is not explicitly AEC-Q100 certified as a standalone part, its B-grade specifications and qualification testing align with automotive-grade performance expectations for cabin and non-safety-critical modules.
