SGM8582
Single-Supply, Dual Rail-to-Rail I/O
Precision Operational Amplifier
PRODUCT DESCRIPTION
The SGM8582 is a dual rail-to-rail input and output
precision operational amplifier which has low input offset
voltage, and bias current. It is guaranteed to operate
from 2.5V to 5.5V single supply.
The rail-to-rail input and output swings provided by the
SGM8582 make both high-side and low-side sensing
easy. The combination of characteristics makes the
SGM8582 good choices for temperature, position and
pressure sensors, medical equipment and strain gauge
amplifiers, or any other 2.5V to 5.5V application requiring
precision and long term stability.
The SGM8582 is specified for the extended industrial/
automotive (-40to +125℃) temperature range. The
SGM8582 comes in the Green SOIC-8 and MSOP-8
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.
