PRODUCT DESCRIPTION
The SGM721 (single), SGM722 (dual), SGM723 (single with
shutdown)
and SGM724 (quad)
are low noise, low voltage,
and low power operational amplifiers, that can be designed
into a wide range of applications. The SGM721/2/3/4 have a
high Gain- Bandwidth Product of 10MHz, a slew rate of
8.5V/μs, and a quiescent current of 0.97mA/amplifier at 5V.
The SGM723 has a power-down disable feature that
reduces the supply current to 160nA.
The SGM721/2/3/4 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 is 4mV for SGM721/2/3/4.
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, SGM721 is available in SC70-5, SOT23-5
and SO-8 packages. SGM723 is available in SOT23-6 and
SO-8 packages. The dual version SGM722 is available in
SO-8 and MSOP-8 packages.
The quad version SGM724 is
970µA, 10MHz, Rail-to-Rail I/O
CMOS Operational Amplifier

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.
