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
● Ultra Low Power Consumption:
typical power supply current of 300nA (per channel). It
300nA/Channel (TYP) at VS = 1.4V
has the best-in-class power supply current versus
● Wide Supply Voltage Range: 1.4V to 5.5V
propagation delay performance. The propagation delay is
● Propagation Delay: 6μs (TYP) at VS = 1.4V
as low as 6μs with 100mV overdrive at 1.4V supply.
● Push-Pull Output Current Drive:
19mA (TYP) at VS = 5V
Designed to operate over a wide range of supply voltages,
● Rail-to-Rail Input
from 1.4V to 5.5V, with guaranteed operation at 1.4V,
● -40℃ to +85℃ Operating Temperature Range
2.5V and 5.0V, the SGM8705 is ideal for use in a variety
● Available in Green SOIC-8 and MSOP-8 Packages
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
APPLICATIONS
device ideal for use in handheld electronics and mobile
phone applications.
RC Timers
Window Detectors
Featuring a push-pull output stage, the SGM8705 allows
IR Receiver
for operation with absolute minimum power consumption
Multivibrators
when driving any capacitive or resistive load.
Alarm and Monitoring Circuits
SGM8705 is available in Green SOIC-8 and MSOP-8
packages. It is rated over the -40°C to +85°C
temperature range.

NOTE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.

CAUTION
This integrated circuit can be damaged by ESD if you don’t pay
attention to ESD protection. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because
very small parametric changes could cause the device not to
meet its published specifications.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get
the latest datasheet.
