SGM8271/2/4
High Voltage Rail-to-Rail
Output Operational Amplifiers
GENERAL DESCRIPTION
The SGM8271 (single), SGM8272 (dual) and SGM8274
(quad) are high voltage operational amplifiers that are
designed to offer a wide input common mode voltage
range and output voltage swing. These devices can
operate from ±2.25V to ±18V dual power supplies or
from +4.5V to +36V single supplies.
The devices feature high slew rate, low input bias and
offset current, low offset voltage and low offset-voltage
temperature coefficient.
The SGM8271/2/4 are specified over the extended -40℃
to +125℃ temperature range. The SGM8271 single is
available in Green SOT-23-5, MSOP-8 and SOIC-8
packages. The SGM8272 dual is available in Green
SOIC-8 and MSOP-8 packages. The SGM8274 quad is
available in Green SOIC-14 and TSSOP-14 packages.

NOTES:
1. 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.
2. Proper power-supply sequencing is recommended for the
CMOS device. Always sequence V
S
on first, followed by the
inputs and outputs.

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.
