PRODUCT DESCRIPTION
The SGM8631(single), SGM8632(dual), SGM8633(single
with shutdown)
and SGM8634 (quad)
are low noise, low
voltage, and low power operational amplifiers, that can be
designed into a wide range of applications. The
SGM8631/2/3/4 have a high gain-bandwidth product of
6MHz, a slew rate of 3.7V/μs, and a quiescent current of
470μA/amplifier at 5V. The SGM8633 has a power-down
disable feature that reduces the supply current to 90nA.
The SGM8631/2/3/4 are designed to provide optimal
performance in low voltage and low noise systems. They
provide rail-to-rail output swing into heavy loads. The
input common-mode voltage range includes ground, and
the maximum input offset voltage are 3.5mV for
SGM8631/2/3/4. They are specified over the extended
industrial temperature range (−40°C to +125°C). The
operating range is from 2.5V to 5.5V.
The single version, SGM8631/8633, is available in SC70-5,
SO-8 and SOT23-5(6) packages. The dual version SGM8632
is available in SO-8 and MSOP-8 packages.

NOTES
1. Stresses above those listed under Absolute Maximum
Ratings may cause permanent damage to the device. This is
a stress rating only; functional operation of the device at
these or any other conditions above those indicated in the
operational section of this specification 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.
Shengbang Micro-electronics 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.
