摘要
常规电平切割细分电路的细分数越高 ,细分电路所需的比较器也越多 ,会造成电路结构烦杂 ,装调困难 ,这是限制细分数的实际原因。以点 /线显示驱动器LM 3914替代常规电平切割细分电路中的比较器阵列 ,可以减少比较器芯片的使用数量 ,提高电路的集成度 ,增强系统的可靠性。对LM 3914采用级联 。
The number of the comparators used in conventional level based division circuit increases with the increasement of the division number of the circuit, which results in complexity of the circuit structure and inconvinience to assemble the circuit. Therefore, actual division number is limited. By substituting the comparator array used in the conventional level based division circuit with dot/line display driver LM3914, the number of the comparator chips could be reduced, and the integrity of the circuit as well as the reliability of the system could be improved. In addition, concatenation of LM3914s could increase the division number of the circuit effectively.
