Descriptions
The DIO20891/2 is an ultra low-power comparator
with a typical power supply current of 0.3 μA. It
has the best-in-class power supply current versus
propagation delay performance. The propagation
delay is as low as 8 μs with 100 mV overdrive at 1.4
V supply.
Designed to operate over a wide range of supply
voltages, from 1.4 V to 5.5 V, with guaranteed
operation at 1.4 V, 1.8 V, 2.5 V and 5.0 V, the
DIO20891/2 is ideal for use in a variety of
battery-powered applications. With rail-to-rail
common mode voltage range, the DIO20891/2 is
well suited for single-supply or dual-supply
operation.
Featuring a push-pull output stage, the DIO20891/2
allows for operation with absolute minimum power
consumption when driving any capacitive or
resistive load.
The DIO20891/2 is available in the Green SC70-5,
DFN1*1-6, DFN0.8*0.8-4 and DFN1.6*1.2-8
packages. The DIO20891/2 is ideal for use in
handheld electronics and mobile phone
applications. It is rated over the -40°C to 85°C
temperature range.
