Product details
Overview
ADR01AUJZ-REEL7 from Analog Devices is a precision 10.0 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), 20 µVp-p (0.1 Hz–10 Hz) noise, and 10 mA output current. It operates from 12.0 V to 36.0 V input and supports precision data acquisition and high-resolution ADC biasing in space-constrained industrial systems.
For engineers reviewing the ADR01AUJZ-REEL7 datasheet, ADR01AUJZ-REEL7 pinout, ADR01AUJZ-REEL7 application, or ADR01AUJZ-REEL7 equivalent, key selection criteria include its ultracompact TSOT footprint, automotive-grade A-grade qualification, integrated TEMP pin for temperature monitoring, TRIM pin for output adjustment, and compatibility with REF01-based designs requiring 10 V reference stability.
Technical Context
The ADR01AUJZ-REEL7 implements a band gap reference core with on-chip trimming for high initial accuracy and low thermal drift. Its 5-pin TSOT package integrates VIN, VOUT, GND, TEMP, and TRIM terminals-enabling both precision voltage generation and auxiliary temperature sensing via the 550 mV baseline and 1.96 mV/°C sensitivity at the TEMP pin.
It delivers stable 10.0 V output across −40°C to +125°C with ≤70 ppm hysteresis and 50 ppm long-term stability over 1000 hours. Line regulation is 7–30 ppm/V and load regulation is 40–70 ppm/mA (0–10 mA), supporting robust operation under varying supply and load conditions without external capacitors.
Key Specifications

FAQ
What is the maximum input voltage rating for ADR01AUJZ-REEL7?
The ADR01AUJZ-REEL7 has an absolute maximum supply voltage of 36.0 V. Its specified operating range is 12.0 V to 36.0 V, with dropout voltage ≤2 V across temperature and load. Exceeding 36.0 V risks permanent damage per Absolute Maximum Ratings in the datasheet. The device maintains regulation down to 12.0 V, making it compatible with nominal 12 V and 24 V industrial rails.
Does ADR01AUJZ-REEL7 require an external output capacitor for stability?
No, ADR01AUJZ-REEL7 is internally compensated and does not require an external output capacitor for stability under all load conditions up to 10 mA. The datasheet explicitly states "No external capacitor required" and confirms stable operation with capacitive loads ranging from 0 to ≥1 µF. This simplifies design and improves reliability in compact layouts where capacitor placement is constrained.
How is the TEMP pin used in ADR01AUJZ-REEL7?
The TEMP pin on ADR01AUJZ-REEL7 outputs a calibrated analog voltage: 550 mV ±10 mV at 25°C with a linear sensitivity of 1.96 mV/°C. It functions as a ratiometric temperature sensor-enabling system-level thermal compensation without external components. When read by a microcontroller's ADC, it provides direct temperature measurement across −40°C to +125°C, supporting features like reference drift correction or thermal shutdown.
Is ADR01AUJZ-REEL7 pin-compatible with REF01?
Yes, ADR01AUJZ-REEL7 is functionally pin-compatible with REF01 in 5-lead configurations: VIN, VOUT, GND, TEMP (replaces REF01's NC), and TRIM (replaces REF01's ADJ). While REF01 lacks TEMP and TRIM functionality, the pin assignments align-allowing direct PCB replacement in existing REF01 footprints when upgraded firmware or calibration accounts for the added features.
What is the long-term stability specification for ADR01AUJZ-REEL7?
ADR01AUJZ-REEL7 exhibits 50 ppm long-term stability over 1000 hours of operation at 25°C, as specified in the ADR01 Electrical Characteristics table. This noncumulative drift value reflects the worst-case output change during the first 1000-hour period; subsequent periods show significantly lower drift. The specification applies to A-grade devices and supports high-reliability applications such as calibration equipment and metrology instruments.
