FEATURES
PRODUCT DESCRIPTION
• Low Cost
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.

• Small Packaging
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.
