Analog Devices Inc. ADCMP391 单通道比较器
亚德诺半导体 ADCMP391 已知上电状态的单通道比较器是一款单通道、轨到轨输入、低功耗比较器，适用于通用型应用。ADCMP391 采用 2.3V 至 5.5V 单电源供电，电流消耗量极低。ADCMP391 仅消耗 18.6μA 的电源电流，非常适合于电池供电系统。ADCMP391 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 1mV，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。ADCMP391 采用 8 引脚、窄体 SOIC 封装，可确保在 -40°C 到 +125°C 的宽幅温度范围内可靠工作。
In addition, the design of the comparator enables a defined output state upon power-up. The comparator generates a logic low output if the supply voltage is less than the UVLO threshold. The ADCMP391 is available in an 8-lead, narrow body SOIC package and specified to operate over the extended temperature range of -40°C to +125°C.
