一般说明：MAX985EUK+T
MAX985EUK+T/ MAX986 / MAX989 / MAX990 / MAX993 /MAX994单/双/四微功耗比较器具有低压操作和轨到轨输入以及输出。它们的工作电压范围为2.5V至5.5V，使其非常适合3V和5V系统。这些比较器还可在±1.25V至±2.75V的电压下工作双耗材。它们仅消耗11μA的电源电流，同时实现300ns的传输延迟。输入偏置电流通常为1.0pA，输入失调电压通常为0.5mV。内部磁滞确保干净的输出开关，即使输入缓慢移动信号。输出级的独特设计限制了电源电流切换时电涌，实际上消除了电源许多其他比较器的典型故障。的
MAX985EUK+T/ MAX989 / MAX993具有推挽输出吸收电流的阶段。大型内部输出驱动器可实现轨至轨输出摆幅负载高达8mA。 MAX986 / MAX990 / MAX994具有开漏输出级，可以将其拉高VCC高于VEE 6V（最大值）。这些漏极开路版本是电平转换器和双极性至单端转换器的理想选择。单个MAX985采用芯片级封装（UCSP™），大大减少了所需的PC板面积。单个MAX985EUK+T/ MAX986可用采用5引脚SC70封装和双MAX989 / MAX990采用8引脚SOT23封装。
