Voltage Drift (mV)
Methodology & Sources
PPM usually refers to 'Parts Per Million' variation of the nominal value. To calculate the absolute drift in Voltage, multiply the Reference Voltage by the PPM value divided by 1,000,000.
The underlying formula used is:
Vref * (PPM / 1e6) * 1000

Frequently Asked Questions
Why calculate voltage drift?
Precision electronics (like voltage references) drift over time or temperature. This drift is often specified in PPM.
Is this linear?
Yes, PPM is a linear ratio. 1 PPM drift on a 5V reference is 5 microvolts (µV).
