Description

The TS881 device is a single comparator

featuring ultra low supply current (210 nA typical

with output high, V

= 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.
