Analog Devices Inc. ADCMP392 双通道比较器
亚德诺半导体 ADCMP392 已知上电状态的双通道比较器是一款双通道、轨到轨输入、低功耗比较器，适用于通用型应用。ADCMP392 采用 2.3V 至 5.5V 单电源供电，电流消耗量极低。四通道 ADCMP392 仅消耗 22.1μA 的电源电流。ADCMP392 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。ADCMP392 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。ADCMP392 低电压和低电流工作的特性，使其特别适合电池供电系统，例如电池管理/监控、电源检测、窗口比较器、阈值检测器/鉴别器、微处理器系统等。
The ADCMP392 features a common-mode input voltage range of 200mV beyond rails, an offset voltage of mV typical across the full common-mode range, and a UVLO monitor. 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.
Available in a 8-lead, narrow body SOIC package, ADCMP392 is specified to operate over the extended temperature range of −40°C to +125°C. ADCMP392's low voltage and low current operation makes it ideal for battery-powered systems such as battery management/monitoring, power supply detection, window comparators, threshold detectors/discriminators, and microprocessor systems.
