Product details
Overview
ADR366AUJZ-REEL7 from Analog Devices is a precision 3.300 V band gap voltage reference IC with sink/source capability, 25 ppm/°C temperature coefficient (A grade), ±8 mV initial accuracy, and ultralow 9.3 µVp-p (0.1 Hz to 10 Hz) output noise - designed for high-stability analog signal chains in battery-powered instrumentation and automotive sensor interfaces.
For engineers reviewing the ADR366AUJZ-REEL7 datasheet, ADR366AUJZ-REEL7 pinout, ADR366AUJZ-REEL7 application, or ADR366AUJZ-REEL7 equivalent, this page delivers verified electrical specifications, TSOT-5 package layout, real-world load/line regulation behavior, and validated alternative options for precision voltage reference selection in space-constrained, low-power systems.
Technical Context
The ADR366AUJZ-REEL7 implements a curvature-corrected band gap architecture referenced to VOUT (not ground), enabling superior ground-noise rejection. Its proprietary trimming achieves 25 ppm/°C drift over −40°C to +125°C while maintaining 300 mV dropout and no external capacitor requirement.
It delivers ±5 mA sourcing / −1 mA sinking capability with 150–190 µA quiescent current, supports input voltages from 3.6 V to 15 V, and exhibits 0.165 mV/V line regulation and 0.6 mV/mA load regulation (0–5 mA, VIN = 4.2 V) - all specified across full industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.300 V nominal, with ±8 mV (±0.25%) initial tolerance at 25°C - enables direct interface with 3.3 V ADCs and DACs without calibration. |
| Tempco | 25 ppm/°C (A grade, −40°C to +125°C) - ensures ≤ ±3.3 mV total drift over full operating range, critical for portable medical sensors. |
| Noise (0.1–10 Hz) | 9.3 µVp-p - supports 16-bit+ data acquisition where low-frequency noise dominates quantization error. |
| Dropout Voltage | 300 mV - allows operation from 3.6 V supply, compatible with single-cell Li-ion or regulated 3.3 V rails. |
| Quiescent Current | 150–190 µA - enables >10-year battery life in always-on monitoring devices powered by coin cells. |
| Output Current | +5 mA sourcing / −1 mA sinking - drives moderate loads (e.g., op-amp bias networks, SAR ADC references) without external buffers. |
| Long-Term Stability | 50 ppm (1000 hours) - guarantees minimal calibration drift in field-deployed industrial controllers. |
Pinout & Package
ADR366AUJZ-REEL7 uses the 5-lead TSOT (UJ-5) package - 2.1 mm × 1.6 mm × 0.6 mm, lead pitch 0.5 mm - optimized for high-density PCB layouts in portable equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NIC) | Not Internally Connected | Unbonded pad; must be left floating or grounded per PCB layout best practices - no electrical function. |
| 2 (GND) | Ground Reference | Primary return path for internal band gap core and output stage; requires low-impedance connection to system ground plane. |
| 3 (VIN) | Input Supply | Accepts 3.6 V to 15 V; minimum headroom 300 mV above VOUT ensures stable regulation under all load conditions. |
| 4 (VOUT) | Reference Output | Stable 3.300 V source; low output impedance (<1 Ω below 10 kHz) enables direct driving of ADC reference inputs and precision op-amp circuits. |
| 5 (TRIM) | Voltage Trim Terminal | Allows fine adjustment of output via external resistor divider (typically 100 kΩ–1 MΩ); enables system-level calibration to ±0.1%. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow 0.1–10 Hz noise | 9.3 µVp-p - reduces effective resolution loss in slow-sampling applications like thermocouple amplifiers and strain gauge bridges. |
| No external capacitor required | Stable operation with zero input/output capacitance - eliminates BOM cost, board area, and reliability risk from ceramic capacitor aging or microphonics. |
| Sink/source capability | −1 mA sinking / +5 mA sourcing - accommodates bidirectional current flow in ratiometric sensor excitation and active filter biasing. |
| Automotive-grade qualification | Qualified per AEC-Q100 (Grade 1) - supports deployment in engine control units, ADAS sensor modules, and infotainment power management. |
| Compact TSOT-5 footprint | 2.1 mm × 1.6 mm - enables placement adjacent to high-resolution ADCs on dense mixed-signal PCBs without thermal coupling or routing congestion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3433ARJZ-R7 | 3.3 V output, 10 ppm/°C max (B grade), ±2 mV initial accuracy, 300 µA IQ, same UJ-5 package. | Higher accuracy and lower tempco, but 58% higher quiescent current - less suitable for ultra-low-power battery systems. | Select when absolute initial accuracy and long-term drift dominate over battery life; verify thermal design for higher IQ-induced self-heating. |
| REF3333AIDBVR | 3.3 V output, 30 ppm/°C max (A grade), ±10 mV initial accuracy, 12 µA IQ, SOT-23-3 package (no TRIM pin). | Ultra-low power but lacks trim capability and has wider tempco - better for always-on IoT nodes than precision instrumentation. | Choose for energy-harvesting or coin-cell applications where 12 µA IQ is critical and ±10 mV accuracy is acceptable; note missing TRIM pin limits calibration flexibility. |
Compared with ADR366AUJZ-REEL7, ADR3433ARJZ-R7 offers tighter initial accuracy and tempco at higher power cost, while REF3333AIDBVR sacrifices trim capability and stability for extreme low-power operation - making ADR366AUJZ-REEL7 the optimal balance for mid-tier precision, size, and power in industrial and automotive designs.

FAQ
What is the maximum operating temperature range for ADR366AUJZ-REEL7?
The ADR366AUJZ-REEL7 is rated for operation from −40°C to +125°C (A grade). This range is fully specified for all key parameters including output voltage, tempco, and load regulation - making it suitable for under-hood automotive and industrial control applications where ambient temperatures exceed 85°C.
Does ADR366AUJZ-REEL7 require an external output capacitor for stability?
No, ADR366AUJZ-REEL7 is internally compensated and operates stably with zero output capacitance. The datasheet explicitly states "no external capacitor required," and typical performance curves confirm stable transient response without added COUT. Adding capacitance may degrade turn-on settling time or introduce peaking.
Can the TRIM pin of ADR366AUJZ-REEL7 be left unconnected?
No - the TRIM pin (Pin 5) must be either connected to a precision resistor divider for output adjustment or tied directly to VOUT for nominal 3.300 V operation. Leaving it floating risks unpredictable output voltage due to leakage currents; grounding it disables trimming and may cause slight deviation from spec.
What is the short-circuit current limit of ADR366AUJZ-REEL7?
ADR366AUJZ-REEL7 provides inherent short-circuit protection: it delivers up to 25 mA when VIN = 5 V and up to 30 mA when VIN = 15 V into a grounded output. This protects both the device and upstream supply during fault conditions without requiring external current-limiting circuitry.
How does the NIC pin (Pin 1) affect PCB layout for ADR366AUJZ-REEL7?
Pin 1 (NIC) is not internally connected and serves only as a mechanical pad. It may be left unconnected, tied to GND for improved thermal conduction, or routed as a thermal relief - but must never be used as a signal or power node. PCB land pattern should match Analog Devices' recommended UJ-5 footprint to ensure solder joint reliability.
