4.轉數或節距<strong>計數電路</strong>.gif

為了使外面數據線的數字角≠能從轉換器的DBl-DB16輸
入,必須使用DA丁A LOAD端(32腳),令其為邏輯。,將數據
線上的數據裝入計數器。為此事前先令ENABLE端(26腳)為邏
輯1.使DBl-DB16呈高阻態,然后變為邏輯O,讓數據鎖存。
    仿此,AD2S82A也可作為固態控制變壓器使用。
    (3)外拄轉數或節距數計赦器;實際應用時,需要對旋轉變
壓器的轉數、感應同步器的節距數進行計數。利用外接計數器
一些門電路t見圖8 1 6),即可實現此要求。圖8 16中,RC (RIP-
PI,E CI.OCK)和DIR (DIRECTK)N)信號來自RDC。
