Description

The DIO20872B is an ultra-low power comparator

with a typical power supply current of 5 μA. It has the

best-in-class

power

supply

current

versus

propagation delay performance. The propagation

delay is as low as 0.9 μs with a 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 DIO20872B is

ideal for the use in a variety of battery-powered

applications. With a rail-to-rail common-mode voltage

range, the DIO20872B is well suited for single-supply

operation.

Featuring an open-drain output stage, the

DIO20872B allows for operation with absolute

minimum power consumption when driving any

capacitive or resistive load.

The DIO20872B is available in the Green

DFN1.6×1.2-8 and TSOT23-8 packages. The

DIO20872B is ideal for the use in handheld

electronics and mobile phone applications. It is rated

over the -40°C to 85°C temperature range.
