SR12D
NOTES
1. Slope Resistance (R_REF)
The slope resistance is defined as
R_REF =
Change in V_REF over specified current range
The change in reference current
2. Reference Voltage Temperature Coefficient (TCV_REF)
This is the normalised reference voltage change over
temperature , divided by the change in temperature. It is
expressed in ppm/°C as follows:
TCV_REF =
∆V_REF x 10⁶
V_REF x ∆T
ppm/°C
∆T = temperature change in °C
∆V_REF = change in reference voltage over temperature
change ∆T.
