Descriptions
The DIO20871B is an ultra low-power comparator
with a typical power supply current of 1.35 μA. It
has the best-in-class power supply current versus
propagation delay performance. The propagation
delay is as low as 1.3 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, 2.5 V and 5.0 V, the DIO20871B
is ideal for use in a variety of battery-powered
applications. With rail-to-rail common mode
voltage range, the DIO20871B is well suited for
single-supply operation.
Featuring an open drain output stage, the
DIO20871B allows for operation with absolute
minimum power consumption when driving any
capacitive or resistive load.
The DIO20871B is available in the Green SOT23-5
and DFN0.8*0.8-4 packages. The DIO20871B is
ideal for use in handheld electronics and mobile
phone applications. It is rated over the -40°C to
85°C temperature range.
