SGM8931/2/3/4
1.5MHz, Rail-to-Rail Output
Operational Amplifiers
PRODUCT DESCRIPTION
The SGM8931 (single), SGM8932 (dual), SGM8933
(single with shutdown) and SGM8934 (
quad
) are
rail-to-rail
output
operational
amplifiers
that
are
optimized and fully specified for 5V operation.
The SGM8931/2/3/4 have a wide input common mode
voltage range and output voltage swing, and take the
minimum operating supply voltage down to 1.8V. The
maximum recommended supply voltage is 5.5V.
The SGM8931/2/3/4 provide excellent overall performance.
They exhibit low noise, distortion and low offset, making
these devices an excellent choice for high quality, low
voltage or battery powered systems.
The SGM8931/2/3/4 are specified over the extended -40℃
to +85℃ temperature range. The SGM8931 single is
available in Green SOT-23-5, SC70-5, MSOP-8 and
SOIC-8 packages. The SGM8932 dual is available in
Green SOIC-8 and MSOP-8 packages. The SGM8933
single with shutdown is available in Green SOT-23-6,
MSOP-8 and SOIC-8 packages. The SGM8934 quad is
available in Green SOIC-14 and TSSOP-14 packages.

NOTE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
CAUTION
This integrated circuit can be damaged by ESD if you don’t pay
attention to ESD protection. 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
very small parametric changes could cause the device not to
meet its published specifications.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get
the latest datasheet.
