SGM8951/2
110kHz, Rail-to-Rail Input and
Output Operational Amplifiers
PRODUCT DESCRIPTION
The SGM8951 (single) and SGM8952 (dual) are
high-performance
CMOS
operational
amplifiers
optimized for low supply operation. These amplifiers are
designed to operate on single supplies from 1.8V to 5.5V.
Applications include sensor amplification and signal
conditioning in battery-powered systems.
The SGM8951/2 offer excellent CMRR without the
crossover
distortion
associated
with
traditional
complimentary input stages. This results in excellent
linearity performance. The input common mode range
includes both the negative and positive supplies.
The SGM8951/2 provide excellent overall performance.
They exhibit low offset, making these devices an
excellent choice for high quality, low voltage or battery
powered systems.
SGM8951 single is available in Green SOT-23-5 and
SOIC-8 packages. The SGM8952 dual is available in
Green SOIC-8 and MSOP-8 packages. The SGM8951/2
are specified over the extended -40
℃
temperature range.
to +85
℃

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.

NOTE 1: Correct power supply bypassing is very important for optimizing SGM8951/2 performance. A 0.1µF and a 10µF capacitors
are always used to bypass V
S
pin of SGM8951/2. Please place these two capacitors as close to the SGM8951/2 V
S
pin as possible. A
large ground plane is also needed to ensure optimum performance.
