SGM8941 datasheet, circuit
SGM8941/2
1.5MHz, Rail-to-Rail Input and
Output Operational Amplifiers
PRODUCT DESCRIPTION
The SGM8941 and SGM8942 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 SGM8941 and SGM8942 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 SGM8941/2 provide excellent overall performance.
They exhibit low noise and offset, making these devices
an excellent choice for high quality, low voltage or
battery powered systems.
The SGM8941 single is available in Green SOT-23-5
and SOIC-8 packages. The SGM8942 dual is available
in Green SOIC-8 and MSOP-8 packages. They are
specified over the extended -40to +85temperature
range.

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.
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 SGM8941/2 performance. A 0.1µF and a 10µF capacitors
are always used to bypass VS pin of SGM8941/2. Please place these two capacitors as close to the SGM8941/2 VS pin as possible. A
large ground plane is also needed to ensure optimum performance.
