查询词典 comparators

Ideal for 3V or 5V single-supply applications, these devices operate from a single +2.5V to +11V supply (or 1.25V to 5.5V dual supplies), and each comparators input voltage ranges from the negative supply rail to within 1.3V of the positive supply.

为3V或5V单电源应用的理想选择，这些器件工作于+2.5 V至+11单电源电压（1.25V至5.5V的或双电源），并在为1.3V从负供电轨每个比较器输入电压范围的正电源。

The ADC is pipelined, including a single-input/difference-output sample/hold circuit and nine stage subcircuits.
