SGM8770
High Voltage, High Precision,
Dual Differential Comparator
GENERAL DESCRIPTION
FEATURES
The SGM8770 is a dual, high precision differential
voltage comparator optimized for high voltage operation.
The device can operate from 2.8V to 36V single supply
or from ±1.4V to ±18V dual power supplies. It
consumes low supply current without being affected by
the supply voltage. Input common mode voltage is 1.5V
lower than +VS. The SGM8770 has an open-drain
output structure that needs external pull-up resistor.

High Voltage, High Precision,
Dual Differential Comparator
SGM8770
DETAILED DESCRIPTION
The SGM8770 is a dual, high precision, low power
comparator. The wide input voltage range and power
supply range make the device a good choice for industrial
equipment. Open-drain structure needs external pull-up
resistor. The SGM8770 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
+VS
In Figure 1, the SGM8770 has an open-drain output
stage. When output is changed from logic high to low,
the changed sink current pulls output pin to logic low.
Beginning this transition, larger sink current is used to
create a high slew rate transit from high to low. Once
the output voltage reaches VOL, it will reduce the sink
current to a just right value to maintain the VOL static
condition. This current-driven open-drain output stage will
significantly reduce the power consumption in application
system.

APPLICATION INFORMATION
For grounding, unbroken and low-inductance ground
plane is a good choice.
Layout and Bypassing
Good power supply decoupling, layout and grounding
are very important for SGM8770 to realize the full
high-speed capabilities in system, following skills will be
used:
For Layout, use short PCB trace to avoid unwanted
parasitic feedback around the comparator. SGM8770
must be soldered directly to the PCB and the socket is
not recommended.
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.
