SGM8701
Micro-Power, CMOS Input, RRIO, 1.4V,
Push-Pull Output Comparator
GENERAL DESCRIPTION
FEATURES
The SGM8701 is an ultra low power comparator with a
● Ultra Low Power Consumption:
typical power supply current of 300nA. It has the
300nA (TYP) at VS = 1.4V
best-in-class power supply current versus propagation
● Wide Supply Voltage Range: 1.4V to 5.5V
delay performance. The propagation delay is as low as
● Propagation Delay: 6μs (TYP) at VS = 1.4V
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 SGM8701 is ideal for use in a variety
● Available in Green SOT-23-5 and SC70-5 Packages
of battery-powered applications. With rail-to-rail common
mode voltage range, the SGM8701 is well suited for
single-supply operation. Its small packages make this
device ideal for use in handheld electronics and mobile
phone applications.
APPLICATIONS
RC Timers
Featuring a push-pull output stage, the SGM8701 allows
Window Detectors
for operation with absolute minimum power consumption
IR Receiver
when driving any capacitive or resistive load.
Multivibrators
Alarm and Monitoring Circuits
SGM8701 is available in Green SOT-23-5 and SC70-5
space-saving packages. It is rated over the -40°C to
+85°C temperature range.

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.
