TS881
Rail-to-rail 0.9 V nanopower comparator
Datasheet
-
production data
Description
The TS881 device is a single comparator
featuring ultra low supply current (210 nA typical
with output high, V
CC
= 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.
