Figure 19: SED1569D0B/SED1569DBB (Temperature Gradient = –0.05%/°C Model
The V5 voltage as a function of the V5 voltage regulator internal resistor ratio register and the electronic
volume register.
Setup example: When selecting Ta = 25°C and V5 = 7
V for an SED1567 model on which Temperature gradient
= –0.05%/°C.
Using Figure 15 and the equation A-1, the following
setup is enabled.
