Product details
Overview
ADR360AUJZ-REEL7 from Analog Devices is a precision 2.048 V band gap voltage reference IC with sink/source capability, 25 ppm/°C temperature coefficient (A grade), ±6 mV initial accuracy, and ultralow 6.8 µVp-p (0.1 Hz to 10 Hz) output noise - designed for high-stability analog signal chains in battery-powered data acquisition systems.
For engineers reviewing the ADR360AUJZ-REEL7 datasheet, ADR360AUJZ-REEL7 pinout, ADR360AUJZ-REEL7 application, or ADR360AUJZ-REEL7 equivalent, this device delivers low dropout (300 mV), 190 µA max quiescent current, and stable operation from −40°C to +125°C without external capacitors - critical for portable medical instruments and industrial process controls requiring long-term drift < 50 ppm over 1000 hours.
Technical Context
The ADR360AUJZ-REEL7 uses proprietary curvature-corrected band gap architecture where the reference is referenced to VOUT-not ground-enabling strong rejection of ground noise. Its PTAT voltage generation relies on unequal current densities across PNP transistor pair Q53/Q52, amplified by resistor ratio 2×(R59/R54).
Temperature drift compensation is achieved via laser-trimmed resistors (R44/R59), one linearly temperature-dependent, enabling 25 ppm/°C performance in the TSOT-5 package. The device operates with no external capacitor and supports bidirectional load current: +5 mA sourcing and −1 mA sinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048 V nominal; tightly regulated ±6 mV at 25°C - enables precise ADC/DAC biasing and sensor excitation without calibration. |
| Temp Coefficient | 25 ppm/°C (A grade, −40°C to +125°C) - ensures ≤±0.62 mV total drift across full operating range. |
| Voltage Noise | 6.8 µVp-p (0.1 Hz to 10 Hz) - minimizes low-frequency error in high-resolution 16–24-bit data converters. |
| Dropout Voltage | 300 mV - allows operation from supply as low as 2.35 V, supporting single-cell Li-ion or dual-cell alkaline systems. |
| Quiescent Current | 190 µA maximum - extends battery life in always-on portable instrumentation. |
| Load Current | +5 mA sourcing / −1 mA sinking - drives ADC reference inputs, op-amp bias networks, and small DAC loads directly. |
| Long-Term Stability | 50 ppm over 1000 hours - guarantees predictable aging behavior in field-deployed equipment. |
Pinout & Package
ADR360AUJZ-REEL7 is housed in a 5-lead TSOT (UJ-5) package - compact, surface-mount, and optimized for thermal performance (θJA = 230°C/W). The package supports reflow soldering per JEDEC J-STD-020 and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NIC) | Not Internally Connected | No internal bond wire; must be left floating or grounded per PCB layout best practice - no electrical function. |
| 2 (GND) | Reference Ground | Primary return path for internal band gap core; requires low-impedance connection to system ground plane. |
| 3 (VIN) | Input Supply | Accepts 2.35 V to 15 V; minimum headroom 300 mV above VOUT ensures regulation integrity. |
| 4 (VOUT) | Stable Reference Output | Delivers 2.048 V with < 100 ppm hysteresis; connects directly to ADC REF+, DAC VREF, or op-amp gain-setting nodes. |
| 5 (TRIM) | Output Voltage Adjustment | Allows fine-tuning 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 | 6.8 µVp-p - preserves SNR in precision weigh scales and portable ECG front-ends. |
| No external capacitor required | Stable with zero output capacitance - eliminates BOM cost, board area, and capacitor aging effects. |
| Sink/source capability | −1 mA to +5 mA output drive - powers reference buffers and compensates for ADC input bias currents. |
| Low dropout | 300 mV headroom - enables use with buck regulators or LDOs delivering ~2.35 V, reducing power loss. |
| Automotive-qualified variants available | H-grade option rated −40°C to +150°C - confirms robustness for under-hood sensor modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR340ARJZ-R7 | Same 2.048 V output, but 10 ppm/°C (B grade), ±2 mV initial accuracy, 3.3 µVp-p noise - higher precision, higher cost. | Better suited for metrology-grade instruments where < 10 ppm drift is mandatory. | Select ADR340ARJZ-R7 only if tighter initial accuracy and lower noise justify premium pricing and longer lead times. |
| REF3020AIDBZR | 2.048 V, 50 ppm/°C, ±10 mV accuracy, 28 µVp-p noise, 65 µA IQ - lower power but significantly higher noise and drift. | Acceptable for cost-sensitive consumer IoT sensors where 16-bit resolution suffices. | Choose REF3020AIDBZR when ultra-low quiescent current (65 µA) outweighs noise/drift requirements. |
Compared with ADR360AUJZ-REEL7, ADR340ARJZ-R7 offers superior accuracy and noise for lab-grade systems, while REF3020AIDBZR trades performance for lower cost and power - making ADR360AUJZ-REEL7 the optimal balance for industrial and portable medical designs needing proven 25 ppm/°C stability and 6.8 µVp-p noise.

FAQ
What is the operating temperature range for ADR360AUJZ-REEL7?
The ADR360AUJZ-REEL7 is rated for −40°C to +125°C operation (A grade). This range is validated per datasheet Table 2 and supports deployment in industrial control cabinets and portable medical devices exposed to wide ambient shifts. It is not rated for automotive under-hood use unless upgraded to H-grade variants like ADR365WHUJZ-R7.
Does ADR360AUJZ-REEL7 require an output capacitor for stability?
No, ADR360AUJZ-REEL7 is internally compensated and stable with zero output capacitance - confirmed in the General Description and Applications Information sections of Rev. E datasheet. Adding an output capacitor may degrade transient response and is unnecessary for basic regulation.
What is the purpose of the TRIM pin on ADR360AUJZ-REEL7?
The TRIM pin (Pin 5) allows adjustment of the output voltage using an external resistor divider. As described in Table 10 and Figure 2, it enables system-level calibration to compensate for PCB trace resistance, ADC offset, or sensor nonlinearity - typically achieving ±0.5% fine-tuning range.
Can ADR360AUJZ-REEL7 sink current, and how much?
Yes, ADR360AUJZ-REEL7 can sink up to −1 mA, as specified in Table 2 under "OUTPUT CURRENT" and confirmed in the GENERAL DESCRIPTION. This capability supports active discharge of reference node capacitance and compensation for op-amp input bias currents in precision buffer configurations.
Is ADR360AUJZ-REEL7 pin-compatible with other members of the ADR36x family?
Yes - all ADR360/ADR361/ADR363/ADR364/ADR365/ADR366 variants share identical 5-lead TSOT (UJ-5) pinout (Figure 2), including NIC, GND, VIN, VOUT, and TRIM. This allows drop-in replacement across output voltages (2.048 V to 5.000 V) when board layout accommodates the specific VOUT requirement.
