GENERAL DESCRIPTION
FEATURES
The SGM8967-1/2/3/4 are a family of single, dual and
● Input Offset Voltage: 240μV (MAX)
quad rail-to-rail input and output operational amplifiers,
● High Gain-Bandwidth Product: 27MHz
which are optimized for low voltage, low noise and high
● High Slew Rate: 30V/μs
precision operation. These devices can operate from
● Settling Time to 0.1% with 2V Step: 120ns
2.1V to 5.5V single supply, while consuming only
● Overload Recovery Time: 60ns
2.7mA quiescent current per amplifier at 5.5V. The
● Low Noise: 8nV/√Hz at 10kHz
supply current of SGM8967-3 is 0.1μA in power-down
● Rail-to-Rail Input and Output
mode.
● Supply Voltage Range: 2.1V to 5.5V
The SGM8967-1/2/3/4 feature a 240μV maximum input
offset. They exhibit a high gain-bandwidth product of
27MHz and a slew rate of 30V/μs. These specifications
make the operational amplifiers appropriate for various
applications.
The SGM8967-1 is available in Green SOT-23-5 and
SOIC-8 packages. The SGM8967-2 is available in
Green SOIC-8 and MSOP-8 packages. The SGM8967-3
is available in a Green SOT-23-6 package. The
SGM8967-4 is available in Green SOIC-14 and
TSSOP-14 packages. They are specified over the
extended industrial temperature range (-40 ℃
+125℃).

may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.
ESD SENSITIVITY CAUTION
Operating Temperature Range ..................... -40℃ to +125℃
This integrated circuit can be damaged if ESD protections are
not considered carefully. 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 even small parametric changes could cause the
device not to meet the published specifications.
OVERSTRESS CAUTION
DISCLAIMER
RECOMMENDED OPERATING CONDITIONS
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods

APPLICATION INFORMATION
Rail-to-Rail Input
When SGM8967-1/2/3/4 work at the power supply
between 2.1V and 5.5V, the input common mode
voltage range is from (-VS) - 0.1V to (+VS) + 0.1V. In
Figure 1, the ESD diodes between the inputs and the
power supply rails will clamp the input voltage not to
exceed the rails.
Driving Capacitive Loads
The SGM8967-1/2/3/4 are designed for unity-gain stable
for capacitive load up to 470pF. If greater capacitive
load must be driven in application, the circuit in Figure 3
can be used. In this circuit, the IR drop voltage
generated by RISO is compensated by feedback loop.

Input Current-Limit Protection
For ESD diode clamping protection, when the current
flowing through ESD diode exceeds the maximum
rating value, the ESD diode and amplifier will be
damaged, so current-limit protection will be added in
some applications. One resistor is selected to limit the
current not to exceed the maximum rating value. In
Figure 2, a series input resistor is used to limit the input
current to less than 10mA, but the drawback of this
current-limit resistor is that it contributes thermal noise
at the amplifier input. If this resistor must be added, its
value must be selected as small as possible.

Power Supply Decoupling and Layout
A clean and low noise power supply is very important in
amplifier circuit design, besides of input signal noise,
the power supply is one of important source of noise to
the amplifiers through +VS and -VS pins. Power supply
bypassing is an effective method to clear up the noise
at power supply, and the low impedance path to ground
of decoupling capacitor will bypass the noise to GND.
In application, 10μF ceramic capacitor paralleled with
0.1μF or 0.01μF ceramic capacitor is used in Figure 4.
The ceramic capacitors should be placed as close as
possible to +VS and -VS power supply pins.

Rail-to-Rail Output
The SGM8967-1/2/3/4 support rail-to-rail output operation.
In single power supply application, for example, when
+VS = 5.5V, -VS = GND, 10kΩ load resistor is tied from
OUT pin to VS/2, the typical output swing range is from
0.008V to 5.492V.

APPLICATION INFORMATION (continued)
Grounding
In low speed application, one node grounding technique
is the simplest and most effective method to eliminate
the noise generated by grounding. In high speed
application, the general method to eliminate noise is to
use a complete ground plane technique, and the whole
ground plane will help distribute heat and reduce EMI
noise pickup.

Difference Amplifier
The circuit in Figure 5 is a design example of classical

Reduce Input-to-Output Coupling
To reduce the input-to-output coupling, the input traces
must be placed as far away from the power supply or
output traces as possible. The sensitive trace must not
be placed in parallel with the noisy trace in same layer.
They must be placed perpendicularly in different layers
to reduce the crosstalk. These PCB layout techniques
will help to reduce unwanted positive feedback and
noise.

Active Low-Pass Filter
The circuit in Figure 7 is a design example of active
low-pass filter, the DC gain is equal to -R2/R1 and the
-3dB corner frequency is equal to 1/2πR2C. In this design,
the filter bandwidth must be less than the bandwidth of
the amplifier, the resistor values must be selected as
low as possible to reduce ringing or oscillation generated
by the parasitic parameters in PCB layout.
