SBVS299A April 2017 – September 2025 REF31-Q1
PRODUCTION DATA
The REF31xx-Q1 is designed to exhibit minimal drift error, defined as the change in output voltage over varying temperature. The drift is calculated using the box method, which is described in Equation 2:
The REF31xx-Q1 features a typical drift coefficient of 5 ppm from 0°C to 70°C, the primary temperature range for many applications. For the industrial temperature range of –40°C to +125°C, the REF31xx-Q1 family drift increases to a typical value of 10 ppm.
