STMicroelectronics' TS880 is a single nanopower, open-drain comparator. It features an ultra-low supply current of 250 nA typical per operator with rail-to-rail input capability and an open-drain output. The performance of this comparator allows it to be used in a wide range of portable applications. The TS880 minimizes battery supply leakage, and therefore, enhances battery lifetime. Operating from 0.9 V to 5.5 V supply voltage, this comparator can be used over a wide temperature range of -40°C to +125°C, thereby keeping the current consumption at an ultra-low level.
