SGM721/2/3/4
11MHz, Rail-to-Rail I/O
CMOS Operational Amplifiers
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
11MHz and a slew rate of 8.5V/μs. The SGM723 has a
power-down disable feature that reduces the supply
current to less than 1μA.
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 supply range is from 2.1V to
5.5V.
The single version, SGM721 is available in Green
SC70-5, SOT-23-5 and SOIC-8 packages. SGM723 is
available in Green SOT-23-6 and SOIC-8 packages.
The dual version SGM722 is available in Green SOIC-8,
MSOP-8 and TSSOP-8 packages. The quad version
SGM724 is available in Green SOIC-14 and TSSOP-14
packages.
