SGM8275-1/SGM8275-2
600kHz, Low Noise, High Voltage,
Precision Operational Amplifiers
GENERAL DESCRIPTION
FEATURES
The SGM8275-1/2 are a family of single and dual
operational amplifiers, which are optimized for high
voltage, low noise and low offset voltage operation.
These devices can operate from 3.6V to 36V single
supply or from ±1.8V to ±18V dual power supplies,
while consuming 0.75mA quiescent current per amplifier.
● Low Offset Voltage: 35μV (TYP), 150μV (MAX)
● Low Bias Current: ±1nA (TYP)
● High Open-Loop Voltage Gain: 130dB at VS = ±15V
● High PSRR: 135dB
● Gain-Bandwidth Product: 600kHz
● Low Noise: 8.5nV/ Hz at 1kHz
√
● Rail-to-Rail Output
The SGM8275-1/2 feature a 150μV maximum input
offset voltage. The output swing is rail-to-rail with heavy
loads. They exhibit a gain-bandwidth product of 600kHz
and a slew rate of 3V/μs. These specifications make the
operational amplifiers appropriate for various applications.
● Supply Voltage Range:
3.6V to 36V or ±1.8V to ±18V
● Input Common Mode Voltage Range:
(-VS) + 1.5V to (+VS) - 2V
● Low Quiescent Current: 0.75mA/Amplifier (TYP)
● -40℃ to +125℃ Operating Temperature Range
● Small Packaging:
The SGM8275-1 is available in a Green SOT-23-5
package. The SGM8275-2 is available in a Green
SOIC-8 package. They are specified over the extended
-40℃ to +125℃ temperature range.

ESD SENSITIVITY CAUTION
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.

APPLICATION INFORMATION
Power Supply Decoupling and Layout
Typical Application Circuits
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 amplifier 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 1.
The ceramic capacitors should be placed as close as
possible to +VS and -VS power supply pins.
Difference Amplifier
The circuit in Figure 2 is a design example of classical
difference amplifier. If R4/R3 = R2/R1, then VOUT = (VP -
VN) × R2/R1 + VREF
.

High Input Impedance Difference Amplifier
The circuit in Figure 3 is a design example of high input
impedance difference amplifier, the added amplifiers at
the input are used to increase the input impedance and
eliminate drawback of low input impedance in Figure 2.

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.

Figure 3. High Input Impedance Difference Amplifier
Active Low-Pass Filter
The circuit in Figure 4 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.
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.
