<p><span>PS508<span> </span></span><span>和</span><span><span> </span>PS509<span> </span></span><span>提供单端或差分配置。单个</span><span><span> </span>PS509<span> </span></span><span>提供差分</span><span><span> </span>4:1<span> </span></span><span>或双重</span><span><span> </span>4:1<span> </span></span><span>讯号端信道。</span><span>PS508<span> </span></span><span>为单端切换提供了</span><span><span> </span>8:1<span> </span></span><span>的比率。地址线用于选择输入</span><span>/</span><span>输出组合，而启用脚位在过低时停用所有切换器。</span></p>
<p><span>0.9pC<span> </span></span><span>的低电压注入</span><span>，</span><span>加上低输入和输出电容</span><span><span> </span>(30pF<span> </span></span><span>或更低</span><span>)</span><span>，</span><span>可确保所切换讯号的低失真。对于工业产品应用来说这非常重要，任一微小的传感器讯号变化都会影响整体系统的功能性。</span></p>
<p><span>多路</span><span>复用</span><span>器可运作的工业温度范围为</span><span><span> </span>-40°C<span> </span></span><span>至</span><span><span> </span>+125°C</span><span>，</span><span>双供应电压在</span><span><span> </span>±5V<span> </span></span><span>和</span><span><span> </span>±18V<span> </span></span><span>之间</span><span>，</span><span>或单供应电压在</span><span><span> </span>10V<span> </span></span><span>和</span><span><span> </span>36V<span> </span></span><span>之间。此两种装置的供应电流固定为</span><span><span> </span>135μA</span><span>，适合可携式产品应用。</span></p>
<p><span>模拟多任务器的一个关键参数是供应电压为</span><span><span> </span>±15V<span> </span></span><span>时</span><span>，</span><span>其低导通电阻为</span><span><span> </span>125</span><span>Ω</span><span>。除了低导通电阻外，低漏电流和低电荷注入将有助于防止讯号损耗和衰减，减少输出讯号的误差，提高后端</span><span><span> </span>ADC<span> </span></span><span>分析的讯号质量。此装置亦具有</span><span><span> </span>75ns<span> </span></span><span>的快速先断后通时间</span><span><span> </span>(</span><span>最小</span><span><span> </span>30ns)</span><span>，过渡时间为</span><span><span> </span>171ns (</span><span>最大</span><span><span> </span>310ns)</span><span>。这减少了从输入到输出的传播时间，支持实时产品应用。此切换器亦提供低泄漏电流，可用于与高阻抗讯号来源介接的产品应用。</span></p>
