SGM721/2/3/4
970μA,10MHz, Rail-to-Rail I/O
CMOS Operational Amplifiers
PRODUCT DESCRIPTION
FEATURES
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 0.16μA.

Low Supply Current
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℃ to +125℃). The
operating range is from 2.5V to 5.5V.
