SGM8708
Micro-Power, RRIO, 1.8V, Dual Push-Pull Output
Comparator with Integrated Voltage Reference
GENERAL DESCRIPTION
FEATURES
The SGM8708 is a dual, rail-to-rail input and output
comparator with typical 2.2µA low power supply current.
The comparator operates from a wide range of 1.8V to
5.5V supply voltage, and is guaranteed to operate at
1.8V and 5V. This feature is suitable for battery-powered
applications.
● Low Quiescent Current:
2.2µA (TYP) at VS = 1.8V
●
VOUT and VOUT Dual Outputs
● Wide Single-Supply Voltage Range: 1.8V to 5.5V
● Latch Function Included
● Rail-to-Rail Input and Output
The product features an uncommitted internal voltage
reference, comparator input common-mode around
200mV outside the power supply rails and can be
operated from 1.8V to 5.5V. The internal 1.2V series
reference voltage offers low 42µV/℃ drift, is stable at
10nF capacitive load, and can produce output current up
to 2mA (TYP).
● Push-Pull Output Current Drive:
18mA (TYP) at VS = 5V
● Internal 1.2V Reference Voltage
● -40℃ to +85℃ Operating Temperature Range
● Available in Green SOT-23-8 and SOIC-8 Packages
The SGM8708 is optimized for micro-power, single-supply
operation. The push-pull output stage supports
rail-to-rail output swing and allows the operation with
absolute minimum power consumption when driving
any capacitive or resistive load. The SGM8708 also

outputs.
IR Receiver
The SGM8708 is available in Green SOT-23-8 and
SOIC-8 packages. It is rated over the -40°C to +85°C
temperature range.

ABSOLUTE MAXIMUM RATINGS
ESD SENSITIVITY CAUTION
Supply Voltage, +VS to -VS ................................................6V
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.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete 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.
VIN Differential................................................... ±(+VS - (-VS))
Voltage at Input/Output Pins....... (-VS) - 0.3V to (+VS) + 0.3V
Junction Temperature.................................................+150℃

RECOMMENDED OPERATING CONDITIONS
DISCLAIMER
Operating Temperature Range.......................-40℃ to +85℃
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.
