Rail-to-rail 0.9V nanopower single comparator

The TS881 device is a single comparator featuring ultra low supply current (210 nA typical with output high, VCC= 1.2 V, no load) with rail-to-rail input and output capability. The performance of this comparator allows it to be used in a wide range of portable applications. The TS881 device minimizes battery supply leakage and therefore enhances battery lifetime.

Operating from 0.85 V to 5.5 V supply voltage, this comparator can be used over a wide temperature range (-40 to +125 °C) keeping the current consumption at an ultra low level.

The TS881 device is available in the SC70-5 and the SOT23-5 package, allowing great space saving on the PCB.
