  • Description

    The NJU7725x, NJU7726x series are Rail-to-Rail Input CMOS comparators featuring High-Speed. These comparators operate from 2.7V to 5.5V and low supply current of 140µA/ch. typ. This feature is suitable for battery powered application. NJU7725x, NJU7726x 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. NJU7725x, NJU7726x series are available in ultra-small, leadless package measuring 1.6 mm x 1.6 mm (DFN6) and 2.0 mm x 2.0 mm (DFN8), and industrial standard leaded packages SOT-23-5, SC-88A, and MSOP8 (VSP8).
