SGM8708
Micro-Power, RRIO, 1.8V, Dual Push-Pull Output
Comparator with Integrated Voltage Reference
GENERAL DESCRIPTION
The SGM8708 is a low power comparator with a typical
power supply current of 2.2µA. It features an uncommitted
on-chip voltage reference, comparator input common mode
range of 200mV beyond the supply rails, and single-supply
operation from 1.8V to 5.5V. The integrated 1.2V series
voltage reference offers low 42µV/drift, is stable with up
to 10nF capacitive load, and can source up to 2mA (TYP) of
output current.
Designed to operate over a wide range of supply voltages,
from 1.8V to 5.5V, with guaranteed operation at 1.8V and
5.0V, the SGM8708 is ideal for use in a variety of
battery-powered applications. With rail-to-rail input common
mode voltage range, the SGM8708 is well suited for
single-supply operation. Its small packages make this
device ideal for use in handheld electronics and mobile
phone applications.
Featuring a push-pull output stage and having a latch
enable input (LE ), the SGM8708 allows for operation with
absolute minimum power consumption when driving any
capacitive or resistive load.
SGM8708 is available in Green SOT-23-8 and SOIC-8
packages. It is rated over the -40to +85temperature
range.
