Nisshinbo Micro Devices NJU77250 NJU77251
High-speed, Rail-to-Rail input, CMOS comparator
The NJU77250 and NJU77251 series are Rail-to-Rail Input CMOS comparators featuring High-Speed. These comparators operate from 2.7 V to 5.5 V and low supply current of 140 μA/channel. typ. This feature is suitable for battery powered application. The series features the newly developed circuit technology Dynamic Transient Stabilizer TM realizes full swing input with suppressed fluctuation of propagation delay time. In addition, the common mode input voltage range that exceeds the power supply voltage range is specified, and voltage detection near the power supply voltage is supported.
