AD2S80A:  分辨率可变的旋变数字转换器

AD2S80A 功能框图AD2S80A/AD2S81A/AD2S82A 系列是单芯片、10/12/14/16位旋变数字转换器。该转换器允许用户通过外部元件选择所需的分辨率和动态性能。这赋予用户极大的灵活性,从而确定最适合其系统要求的转换器。借助该转换器,用户可以选择10位、12位、14位或16位的分辨率(AD2S81A仅支持12位分辨率);设置为10位分辨率时,可以跟踪转速最高达1040转/秒(62,400 rpm)的旋变信号。AD2S80A/AD2S81A/AD2S82A 系列利用比率跟踪转换方法将旋变格式输入信号转换为并行自然二进制数字字。这样确保具有高抗扰度并支持长引线,从而可将转换器远离旋变器放置。AD2S80A/AD2S81A/AD2S82A 系列的参考频率范围为50 Hz至20,000 Hz。

The AD2S80A/AD2S81A/AD2S82A series are monolithic 10-, 12-, 14, or 16-bit tracking resolver-to-digital converters.The converter allows users to select their own resolution and dynamic performance with external components. This allows the users great flexibility in defining the converter that best suits their system requirements. The converter allows users to select the resolution to be 10, 12, 14, or 16 bits [AD2S81A allows 12 bit resolution only] and to track resolver signals rotating at up to 1040 revs per second (62,400 rpm) when set to 10-bit resolution.The AD2S80A/AD2S81A/AD2S82A series converts resolver format input signals into a parallel natural binary digital word using a ratiometric tracking conversion method. This ensures high noise immunity and tolerance of long leads allowing the converter to be located remote from the resolver.The AD2S80A/AD2S81A/AD2S82A series operates over reference frequencies in the range 50 Hz to 20,000 Hz.
