1. Slope resistance (R )
REF
Slope resistance is defined as
RREF = Change in VREF over a specified current range
The change in reference current
2. Reference voltage temperature coefficient (TC VREF)
This is the normalised reference voltage change over temperature, divided by the change in temperature.
It is expressed in ppm/°C
