Figure 9 : (1) For ST7565S the Thermal Gradient = -0.05%/°C
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 = –7V for an ST7565S on which Temperature gradient = –0.05%/°C.
Using Figure 9 and the equation A-1, the following setup is enabled.
At this time, the variable range and the notch width of the V5 voltage is, as shown Table 13, as dependent on the electronic
volume.
