SGM8702
Micro-Power, CMOS Input, RRIO, 1.4V,
Open Drain Output Comparator
GENERAL DESCRIPTION
FEATURES
The SGM8702 is an ultra low power comparator with a
typical power supply current of 300nA. 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 SGM8702 is ideal for use in a variety
of battery-powered applications. With rail-to-rail common
mode voltage range, the SGM8702 is well suited for
single-supply operation. Its small packages make the
SGM8702 ideal for use in handheld electronics and
mobile phone applications.
Ultra Low Power Consumption:
300nA (TYP) at VS = 1.4V
Wide Supply Voltage Range: 1.4V to 5.5V
Propagation Delay: 6μs (TYP) at VS = 1.4V
Open Drain Output Current Drive:
18mA (TYP) at VS = 5V
Rail-to-Rail Input
P-MOSFET Open Drain Output Structure
-40to +85Operating Temperature Range
Available in Green SOT-23-5 and SC70-5 Packages
TYPICAL APPLICATION
+5V (+3V)
Featuring an open drain output stage, the SGM8702
allows for operation with absolute minimum power
consumption when driving any capacitive or resistive
load.
SGM8702 is available in Green SOT-23-5 and SC70-5
space-saving packages. It is rated over the -40to
+85temperature range.
