SGM8621/2/3/4
3MHz, Rail-to-Rail I/O
CMOS Operational Amplifiers
PRODUCT DESCRIPTION
The SGM8621 (single), SGM8622 (dual), SGM8623
(single with shutdown) and SGM8624 (quad) are low
noise, low voltage, and low power operational
amplifiers, that can be designed into a wide range of
applications. The SGM8621/2/3/4 have a high
gain-bandwidth product of 3MHz and a slew rate of
1.7V/μs. The SGM8623 has a power-down disable
feature that reduces the supply current to less than
1μA.
The SGM8621/2/3/4 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 3mV for
SGM8621/2/3/4. They are specified over the extended
industrial temperature range (-40℃ to +125℃). The
operating supply range is from 2V to 5.5V.
The single version, SGM8621 is available in Green
SC70-5, SOT-23-5 and SOIC-8 packages. SGM8623 is
available in Green SOT-23-6 and SOIC-8 packages.
The dual version SGM8622 is available in Green
SOIC-8 and MSOP-8 packages. The quad version
SGM8624 is available in Green SOIC-14 and
TSSOP-14 packages.
