Low Power, Rail-to-Rail Input Comparator
GENERAL DESCRIPTION
FEATURES
The SGM8750 is a dual, high speed, low power
comparator, which features a fast 300ns propagation
delay. The device is optimized for low voltage operation
on 3V or 5V supply, and consumes only 46μA supply
current.
● Low Propagation Delay: 300ns (Overdrive = 10mV)
● Low Supply Current: 46μA (TYP) at VCC = 3V
● Low Offset Voltage: 5.5mV (MAX)
● Rail-to-Rail Input
● Supply Voltage Range: 2.7V to 5.5V
● Open-Drain Output
The SGM8750 supports rail-to-rail input operation. The
input common mode voltage range is from -0.1V to VCC
+ 0.1V. The device has an open-drain output structure
that needs external pull-up resistor. Any input or output
pin has a continuous short-circuit protection to both
power supply rails.
● Output Swing with 4mA Output Current: 200mV
(TYP)
● Supports CMOS or TTL Logic
● -40℃ to +125℃ Operating Temperature Range
● Available in Green SOIC-8 and MSOP-8 Packages
The SGM8750 is available in Green SOIC-8 and
MSOP-8 packages. It is rated over the -40℃ to +125℃
temperature range.

Low Power, Rail-to-Rail Input Comparator
DETAILED DESCRIPTION
The SGM8750 is a single, high speed, low power
comparator optimized for low voltage operation from
2.7V to 5.5V single supply. The device supports
rail-to-rail input operation. It is suitable for portable
equipment. Open-drain structure needs external pull-up
resistor. The SGM8750 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.
VCC
Output Structure
In Figure 1, the SGM8750 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.

Good power supply decoupling, layout and grounding
are very important for SGM8750 to realize the full
high-speed capabilities in system, following skills will be
used:

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 VCC pin as
possible.

For grounding, unbroken and low-inductance ground
plane is a good choice.

For Layout, use short PCB trace to avoid unwanted
parasitic feedback around the comparator. SGM8750
must be soldered directly to the PCB and the socket is
not recommended.
