SGM8705
Micro-Power, CMOS Input, RRIO, 1.4V,
Push-Pull Output Comparator
GENERAL DESCRIPTION
FEATURES
The SGM8705 is a dual low power comparator with a
typical power supply current of 300nA (per channel). It
has the best-in-class power supply current versus
propagation delay performance. The propagation delay is
as low as 6μs with 100mV overdrive at 1.4V supply.
Designed to operate over a wide range of supply voltages,
from 1.4V to 5.5V, with guaranteed operation at 1.4V,
2.5V and 5.0V, the SGM8705 is ideal for use in a variety
of battery-powered applications. With rail-to-rail common
mode voltage range, the SGM8705 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, the SGM8705 allows
for operation with absolute minimum power consumption
when driving any capacitive or resistive load.
● Ultra Low Power Consumption:
300nA/Channel (TYP) at VS = 1.4V
● Wide Supply Voltage Range: 1.4V to 5.5V
● Propagation Delay: 6μs (TYP) at VS = 1.4V
● Push-Pull Output Current Drive:
19mA (TYP) at VS = 5V
● Rail-to-Rail Input
● -40℃ to +85℃ Operating Temperature Range
● Available in Green SOIC-8 and MSOP-8 Packages
