AD2S83是一款單芯片、10/12/14/16位旋變數(shù)字轉(zhuǎn)換器。
該轉(zhuǎn)換器允許用戶通過(guò)外部器件選擇所需的分辨率和動(dòng)態(tài)性能。借助該轉(zhuǎn)換器,用戶可以選擇10位、12位、14位或16位的分辨率;設(shè)置為10位分辨率時(shí),可以跟蹤轉(zhuǎn)速最高達(dá)1040轉(zhuǎn)/秒(62,400 rpm)的旋變信號(hào)。
AD2S83利用比率跟蹤轉(zhuǎn)換方法將旋變格式輸入信號(hào)轉(zhuǎn)換為并行自然二進(jìn)制數(shù)字字。這樣確保具有高抗擾度并支持長(zhǎng)引線,從而可將轉(zhuǎn)換器遠(yuǎn)離旋變器放置。
A它也可以提供與轉(zhuǎn)速成比例的精密模擬信號(hào),從而取代轉(zhuǎn)速傳感器。AD2S83的參考頻率范圍為0 Hz至20,000 Hz。
