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
