Precision 2.5V reference with 6 ppm/°C drift
The REF3425MDBVTEP: This level of drift means the output shifts less than 1 mV across the entire temperature span — critical for precision ADC references where the reference error directly scales the conversion result.
Noise and load regulation for signal-chain accuracy
The series architecture sources up to 10 mA output current while drawing only 95 µA quiescent supply current, making it suitable for driving multiple ADC reference inputs without a separate buffer. Input voltage range spans 3V to 12V, accommodating common 3.3V, 5V, and 12V rails with headroom for the dropout — the 2.5V output regulates down to a 3V input at full load.
The SOT-23-6 package (supplier device package SOT-23-6) is a standard surface-mount footprint with 0.95 mm pitch, compatible with reflow profiles typical for lead-free assemblies.
