What are the key features of REF3320AIDCKRG4?
- 30 ppm/°C maximum temperature coefficient ensures stable 2.048 V reference across -40°C to 125°C industrial temperature range
- Ultra-low 3.9 µA quiescent current minimizes power consumption in always-on battery-powered sensor nodes
- 3-pin SOT-23 package enables minimal footprint precision voltage reference without external compensation capacitors
What is REF3320AIDCKRG4 used for?
The REF3320AIDCKRG4 provides a stable 2.048 V precision reference for ADC and DAC circuits in industrial and portable measurement equipment. Its 30 ppm/°C drift specification limits reference error to less than 3 mV across the full -40°C to 125°C temperature range, preserving measurement accuracy in thermally variable environments. The 3.9 µA quiescent current makes it suitable for battery-operated data loggers, wearable health monitors, and IoT sensor nodes where supply budget is tightly constrained.

Frequently Asked Questions
How much input headroom is required when REF3320AIDCKRG4 provides a 2.048 V reference?
REF3320AIDCKRG4 operates from a 2.248 V to 5.5 V input range, so designs using its 2.048 V output should allow sufficient supply headroom above the reference voltage.
For compact ADC layouts, what does the 3-pin SOT-23 package offer?
The 3-pin SOT-23 package keeps the voltage-reference footprint small while still supporting one precision output, making it practical near ADC or DAC reference pins.
When is this TI reference a good fit for low-power measurement equipment?
It is well suited to battery-powered sensing or portable instruments because the device draws about 3.9 µA quiescent current and supports up to 5 mA output current.
Which accuracy constraints should buyers verify before approving REF3320AIDCKRG4 for production?
Buyers should confirm the 30 ppm/°C maximum temperature drift and the 2.048 V nominal output meet the system error budget over the required operating temperature range.
