Voltage reference ICs deliver stable, low-drift output voltage for ADCs, DACs, and precision circuits.
Product Overview
A voltage reference IC provides a precise, temperature-stable output voltage independent of supply and load variations, serving as the accuracy anchor for data converters, sensors, and analog front-ends. Series and shunt topologies offer initial accuracies from 0.1% and drift as low as several ppm/°C. Newfly supplies verified voltage reference ICs (TL431-class, LM4040-class, REFxx-class) with cross-reference and BOM-matching support for production sourcing.

FAQ
Q: Fixed or adjustable?
A: Both are available — fixed outputs (e.g., 2.5 V, 3.0 V) and adjustable shunt types; confirm with the datasheet.
Q: How stable is the output?
A: Precision variants offer low ppm/°C drift; verify the exact grade by part number.
Q: Can you provide a cross-reference?
A: Yes. Share your BOM and Newfly will suggest compatible voltage reference ICs.
