SGM8703
Micro-Power, CMOS Input, RRIO,
1.4V, Push-Pull Output Comparator
with Latch Enable
GENERAL DESCRIPTION
The SGM8703 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 SGM8703 is ideal for use in a variety
of battery-powered applications. With rail-to-rail common
mode voltage range, the SGM8703 is well suited for
single-supply operation. Its small package makes this
device ideal for use in handheld electronics and mobile
phone applications.
RC Timers
Featuring a push-pull output stage and has a latch enable
input (
LE
), the SGM8703 allows for operation with
absolute minimum power consumption when driving any
capacitive or resistive load.
SGM8703 is available in the Green SOT-23-6 package. It
is rated over the -40°C to +85°C temperature range.

NOTE: The location of pin 1 on the SGM8703 is determined by
orienting the package marking as shown.
CAUTION
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.
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.
