Product details

5 V reference with 8 ppm/°C drift — the BOM anchor for precision rails

Low-frequency noise is 3 µVp-p from 0.1 Hz to 10 Hz, which sets the noise floor for a 16-bit or 24-bit measurement chain — no post-filter needed for most precision applications. Output current is rated 10 mA, enough to bias the reference input of multiple ADCs or a small sensor bridge without an external buffer.

Input range and supply current — fitting the rail budget

Input voltage range is 5.2 V to 18 V, so it works from a 5.5 V regulated rail up to a 12 V or 15 V system bus. The 1.2 mA quiescent supply current is low enough that the reference does not dominate the power budget in a multi-rail design. The series topology means the output is always within the input minus dropout — no external resistor needed, unlike a shunt reference.

Package and footprint — 8-SOIC layout notes

The surface-mount package is compatible with reflow soldering and common pick-and-place equipment.
