MAX9075

低成本、超小型、3µA、单电源比较器


点击查看特定型号的库存状况。

说明

MAX9075/MAX9077单/双比较器专为3V和5V单电源系统优化设计。传输延迟时间为580ns,每路比较器消耗电流仅3µA。由于综合了低功耗,可低至2.1V单电源工作,超小封装等优点,这组器件尤其适用于各种便携式设备。

MAX9075/MAX9077的共模输入电压范围为-0.2V至VCC - 1.2V。不同于许多其他比较器,此组比较器的输入端没有差动箝位,差动输入压差范围允许到满摆幅。所有输入和输出均能承受连续短路至电源任何一端的故障情况。

特有的输出级设计限制了输出切换时的电源电流浪涌(常见于许多其它比较器),使动态功耗减至最小。内部推挽输出驱动器推动2mA负载时能够提供满摆幅输出,用于连接TTL/CMOS逻辑非常理想。

MAX9075单比较器可提供5引脚SC70和SOT23封装,MAX9077双比较器提供8引脚SOT23、µMAX®及SO封装。
