Embodiment Construction
[0028] in Figure II In the voltage output mode scheme shown, the electronic potentiometer adopts the reverse adjustment method shown in Figure 6, because the resistance network is all connected in parallel. When the count value increases, the output resistance decreases. According to the working principle of TL431, it works normally. Within the range (2.5V-36V), when the resistance value between Vref and A decreases, the voltage between K and A increases. When the resistance value between Vref and A increases, the voltage between K and A increases. When the voltage is reduced, when the resistor network is arranged with an appropriate resistance value according to the 8-4-2-1 code, the linear relationship between the output voltage and the count value can be accurately achieved.
[0029] The same is true Figure three In the voltage output mode scheme shown, the electronic potentiometer adopts Figure Seven In the positive adjustment method shown, when the count value increases, t...
