SGM8772
High Voltage, High Precision,
Dual Differential Comparator with VREF
GENERAL DESCRIPTION
FEATURES
The SGM8772 is a dual, high precision differential
voltage comparator with a voltage reference and a
NAND gate. The device optimized for high voltage
operation from 2.8V to 36V single supply. It consumes
low supply current without being affected by the supply
voltage. Input common mode voltage is 1.5V lower than
+VS. The SGM8772 has a push-pull output structure
without external pull-up resistors. This feature makes it
a good choice for applications whose PCB sizes are
limited. The SGM8772 also provides one window
comparator output.

ESD Susceptibility
This integrated circuit can be damaged if ESD protections are
not considered carefully. 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 even small parametric changes could cause the
device not to meet the published specifications.

High Voltage, High Precision,
SGM8772
Dual Differential Comparator with VREF
DETAILED DESCRIPTION
The SGM8772 is dual, high precision, low power
comparator. The wide input voltage range and power
supply range make the device a good choice for industrial
equipment. Push-pull structure saves external pull-up
resistors. The SGM8772 can be compatible with CMOS
and TTL logics.
If low slew rate transition is needed in system design,
adjusting the load capacitance will change the slew rate.
The heavier capacitive load will slow down the output
voltage transition. This feature will be used to reduce
the interference generated by fast edge of transition
between 1 and 0 in noise-sensitive system.
Output Structure
In Figure 1, the SGM8772 has a push-pull output stage.
When output is changed from logic high/low to low/high,
the changed sink/source current pulls/pushes output
pin to logic low/high. Beginning this transition, larger
sink/source current is used to create a high slew rate
transit from high/low to low/high. Once the output
voltage reaches VOL/VOH, it will reduce the sink/source
current to a just right value to maintain the VOL/VOH
static condition. This current-driven push-pull output
stage will significantly reduce the power consumption in
application system. OUTA, OUTB and NAND gate form
the third window comparator output.

APPLICATION INFORMATION
Window Comparator
Layout and Bypassing
It’s easy to design a window comparator by using
SGM8772, and this design is shown in Figure 2.
Good power supply decoupling, layout and grounding
are very important for SGM8772 to realize the full
high-speed capabilities in system, following skills will be
used:
+5V
0.1μF
A 0.1µF to 4.7µF range ceramic capacitor is used to
provide good power supply decoupling. This ceramic
capacitor must be placed as close to VS pin as
possible.

For grounding, unbroken and low-inductance ground

For Layout, use short PCB trace to avoid unwanted

must be soldered directly to the PCB and the socket is
not recommended.
