Key Features
- Precision 5.0 V output with initial accuracy of ±12 mV (±0.24%) and low temperature coefficient of 50 ppm/°C for stable reference voltage across -40°C to +125°C industrial temperature range
- Ultra-low quiescent current of 50 µA enabling integration into battery-operated portable instruments and always-on monitoring systems with minimal power budget impact
- Compact 6-pin SOT-23 package (SOT23-6) occupying less than 10 mm² board area, ideal for space-constrained ADC reference and DAC reference circuits in handheld devices
Applications
The ADR125AUJZ-R2 is ideal as a precision 5 V voltage reference for 12-bit and 16-bit ADCs and DACs in portable data acquisition systems, medical diagnostic instruments, and industrial sensor interfaces requiring stable reference accuracy over the -40°C to +125°C temperature range. Its 50 µA quiescent current suits battery-powered handheld meters and wearable calibration equipment where supply current must be minimized. The SOT-23-6 package also makes it suitable for tight PCB layouts in smart transmitters and process control loops.

Frequently Asked Questions
What is the output voltage and initial accuracy of the ADR125AUJZ-R2?
The ADR125AUJZ-R2 provides a 5.0 V reference output with an initial accuracy of ±12 mV (±0.24%) and a temperature coefficient of 50 ppm/°C, maintaining stable output across a -40°C to +125°C industrial temperature range without requiring external trimming.
How much quiescent current does ADR125AUJZ-R2 consume, and does it suit battery-powered designs?
The ADR125AUJZ-R2 draws only 50 µA of quiescent current, making it well-suited for battery-powered portable instruments. A standard 2000 mAh Li-ion cell can supply this reference continuously for over 1600 hours when ADR125AUJZ-R2 is the dominant load in always-on sensor monitoring applications.
Which ADC precision levels can ADR125AUJZ-R2 support as a voltage reference?
With a ±12 mV initial accuracy on a 5 V output (0.24% error) and a 50 ppm/°C temperature coefficient, ADR125AUJZ-R2 is suitable as a reference for up to 12-bit ADCs. For higher 16-bit resolution designs requiring sub-1 ppm/°C drift and sub-1 mV accuracy, an upgraded reference such as the ADR4550 series would be more appropriate.
What package does ADR125AUJZ-R2 use, and how compact is the board footprint?
ADR125AUJZ-R2 is housed in a 6-pin SOT-23 package measuring approximately 2.9 mm x 1.6 mm with a 0.95 mm pin pitch. This occupies less than 10 mm² of PCB area, enabling tight reference circuit layouts in handheld meters, portable calibrators, and compact industrial sensor modules.
