SR25D
NOTES
1. Slope Resistance (RREF)
The slope resistance is defined as
RREF =
Change in VREF over specified current range
The change in reference current
2. Reference Voltage Temperature Coefficient (TCVREF)
This is the normalised reference voltage change over
temperature , divided by the change in temperature. It is
expressed in ppm/°C as follows:
TCVREF =
∆VREF x 106 ppm/°C
VREF x ∆T
∆T = temperature change in °C
∆VREF = change in reference voltage over temperature
change ∆T.
