Analog Devices Inc. 亚德诺半导体 ADCMP393 四通道比较器
亚德诺半导体 ADCMP393 四通道比较器是轨到轨输入、低功率比较器，采用 2.3V 到 5.5V 的单电源供电、并接通最低限度的电流。四通道 ADCMP393 仅消耗 26.8μA 的电源电流。ADCMP393 的共模输入电压范围为供电轨以上 200mV，其在整个共模电压范围内的失调电压典型值为 1 mV，并集成欠压闭锁(UVLO)监控器。此外，该比较器在设计上允许输出在上电时具备确定的状态。若电源电压依然低于 UVLO 阈值，则比较器产生逻辑低电平输出。ADCMP393 工作时具有低电压和低电流特性，是电池供电系统的理想选择。
In addition, the design of the comparator allows a defined output state upon power-up. The comparator generates a logic low output while the supply voltage is less than the UVLO threshold. The low voltage and low current operation of the ADCMP393 makes it ideal for battery-powered systems.
