Rb/Ra indicates the V
resistance ratio and can be adjusted into eight steps
using the V
set command. The reference values of the (1+Rb/Ra)
ratio are obtained as listed in Table 11 by setting 3-bit
data in the V
register.
For the internal resistance ratio, a manufacturing
dispersion of up to 7% should be taken into account.
When not within the tolerance, adjust the V
externally mounting Ra and Rb.

temperature gradient device based on the values of the
V
and electronic control register at Ta=25 C.
