Product details
Overview
ADR02AUJZ-REEL7 from Analog Devices is a precision 5.0 V band gap voltage reference in a 5-lead TSOT package, featuring ±0.1% initial accuracy, 9 ppm/°C max temperature coefficient (−40°C to +125°C), 10 µVp-p low-frequency noise (0.1 Hz to 10 Hz), and 10 mA output current capability. It operates from 7.0 V to 36.0 V input and supports precision data acquisition in space-constrained industrial sensors.
For engineers reviewing the ADR02AUJZ-REEL7 datasheet, ADR02AUJZ-REEL7 pinout, ADR02AUJZ-REEL7 application, or ADR02AUJZ-REEL7 equivalent, key selection criteria include its ultracompact TSOT-5 footprint, automotive-grade A-grade qualification, integrated TEMP pin for temperature monitoring, and no external capacitor requirement for stable operation.
Technical Context
The ADR02AUJZ-REEL7 implements a band gap reference core with on-chip trimming for high initial accuracy and low thermal drift. Its TRIM pin enables fine adjustment of output voltage, while the TEMP pin provides a ratiometric 550 mV baseline with 1.96 mV/°C sensitivity for system-level temperature compensation.
Designed for wide-input-voltage operation (7.0 V to 36.0 V), it delivers 5.0 V ±5 mV over −40°C to +125°C with load regulation of 40–70 ppm/mA and line regulation of 7–30 ppm/V. The device achieves 4 µs turn-on settling time and maintains 50 ppm long-term stability over 1000 hours.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±5 mV at 25°C; ensures ADC reference accuracy within 0.1% across full industrial temperature range |
| Initial Accuracy | ±0.1% (±5 mV); eliminates need for post-assembly calibration in high-resolution converter systems |
| Temp Coefficient | 9 ppm/°C maximum (TSOT-5, A grade, −40°C to +125°C); limits drift to <125 µV over full temperature range |
| Voltage Noise | 10 µVp-p (0.1 Hz to 10 Hz); preserves SNR in 16-bit+ data acquisition without external filtering |
| Output Current | 10 mA continuous; drives multiple SAR ADC references or op-amp bias networks directly |
| Supply Range | 7.0 V to 36.0 V; compatible with unregulated 12 V/24 V industrial rails and automotive battery inputs |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Positive supply input | Accepts 7.0 V to 36.0 V; dropout voltage ≤2 V ensures operation even with significant rail sag |
| 2 - GND | Analog ground reference | Must be connected to clean analog ground plane; separates reference return from digital or power grounds |
| 3 - VOUT | Precision 5.0 V output | Low-impedance source for ADCs, DACs, or instrumentation amplifiers; requires local 100 nF ceramic bypass |
| 4 - TEMP | Temperature sensor output | Provides 550 mV @ 25°C with 1.96 mV/°C slope; enables on-board thermal compensation without external sensor |
| 5 - TRIM | Voltage adjustment node | Allows ±0.5% fine-tuning via external resistor divider; used for system-level calibration or tolerance stacking correction |

FAQ
What is the operating temperature range for the ADR02AUJZ-REEL7?
The ADR02AUJZ-REEL7 is specified over the extended industrial temperature range of −40°C to +125°C. This range is guaranteed for all electrical parameters including output voltage accuracy, temperature coefficient, and load regulation. The A-grade qualification also supports automotive under-hood applications meeting AEC-Q100 Grade 1 requirements. Operation outside this range may result in parametric degradation or permanent damage.
Does the ADR02AUJZ-REEL7 require an external output capacitor?
No, the ADR02AUJZ-REEL7 does not require an external output capacitor for stability. Its internal compensation ensures robust operation with capacitive loads up to 100 nF. However, a 100 nF ceramic capacitor placed close to the VOUT pin is recommended to suppress high-frequency noise and improve transient response. Input capacitance is also optional but advised for noisy supply environments.
How is the TEMP pin used in the ADR02AUJZ-REEL7?
The TEMP pin on the ADR02AUJZ-REEL7 outputs a ratiometric voltage of 550 mV at 25°C with a linear sensitivity of 1.96 mV/°C. It can be connected directly to an ADC input to measure die temperature for system-level thermal compensation or fault detection. No external components are needed, and the output remains accurate across the full −40°C to +125°C operating range.
What is the maximum load current supported by the ADR02AUJZ-REEL7?
The ADR02AUJZ-REEL7 delivers up to 10 mA of continuous output current while maintaining specified accuracy and regulation. Load regulation is characterized at 0 mA to 10 mA, with typical drift of 40–70 ppm/mA depending on input voltage and temperature. Exceeding 10 mA may cause output voltage deviation beyond specifications and increased thermal stress.
Is the ADR02AUJZ-REEL7 pin-compatible with the REF02?
Yes, the ADR02AUJZ-REEL7 in TSOT-5 is functionally and pinout-compatible with the REF02 in SOIC-8 at the component level, and Analog Devices explicitly states that ADR02 SOIC and TSOT versions are pin-to-pin replacements for REF02. Pin mapping (VIN, GND, VOUT, TEMP, TRIM) matches REF02's functional pins, though REF02 lacks the TEMP and TRIM pins-meaning those functions are unused in REF02-based designs.
