SGM8261-1/SGM8261-2
Bipolar-Input, High Performance,
Ultra-Low Noise Operational Amplifiers
GENERAL DESCRIPTION
FEATURES
The single SGM8261-1 and dual SGM8261-2 are
bipolar-input, low noise operational amplifiers optimized
for high voltage systems. These devices operate from
3.6V to 36V single supply or from ±1.8V to ±18V dual
power supplies, while consuming 3.8mA quiescent
current per amplifier.
• Excellent Sound Quality
• Ultra-Low Input Voltage Noise: 1.6nV/ Hz at 1kHz
√
• Ultra-Low Distortion: 0.00002% at 1kHz
• Unity-Gain Stable
• Gain-Bandwidth Product: 16MHz (G = +1)
• High Slew Rate: 16V/μs
• High Open-Loop Gain: 140dB
• Low Offset Voltage: ±350μV (MAX)
• Rail-to-Rail Output
The SGM8261-1/2 have impressive dynamic characteristics
with various loads. The rail-to-rail output swing with a
2kΩ load is within 185mV of the rails. This results in
large headroom and wide dynamic range. The
SGM8261-1/2 are unity-gain stable and offer a ±65mA
• Support Single or Dual Power Supplies:
3.6V to 36V or ±1.8V to ±18V
• Low Quiescent Current: 3.8mA/Amplifier
• -40℃ to +85℃ Operating Temperature Range
• Small Packaging:
high output current. They feature 1.6nV/ Hz ultra-low
√
noise at 1kHz with 0.00002% distortion.
The SGM8261-1 is available in a Green SOIC-8
package. The SGM8261-2 is available in Green SOIC-8,
MSOP-8 and TDFN-3×3-8BL packages. They operate
over an ambient temperature range of -40℃ to +85℃.

ESD Susceptibility
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.
