Description

The NJU7721x, NJU7722x series are Rail-to-Rail input comparator featuring ultralow supply current of 0.7µA (single) and 0.6µA/ch (Dual). Designed to operate from 1.7V to 5.5V, and rail-to-rail input voltage range, make them suitable for use in a wide variety of battery-powered single supply applications. The NJU7721x, NJU7722x series features the newly developed circuit technology Dynamic Transient Stabilizer realizes rail-to-rail input with suppressed fluctuation of propagation delay time. Integrated high EMI immunity can reduced malfunctions caused by RF-noises from mobile phones and other electronic devices. Also, the input voltage can be input up to 5.5V beyond the positive supply rail, and no output inversion even in this state. These make them well suited for precision voltage monitoring in harsh, noisy environments. NJU7721x, NJU7722x series are available in ultrasmall, leadless package measuring 1.6 mm x 1.6 mm DFN6-G1 (ESON6-G1) and 2.0 mm x 2.0 mm DFN8-U1 (ESON8-U1), and industrial standard leaded packages SOT-23-5, SC-88A, and MSOP8(VSP8).

Applications
