SGM8631/2/3/4
470μA, 6MHz, Rail-to-Rail I/O
CMOS Operational Amplifiers
PRODUCT DESCRIPTION
The SGM8631 (single), SGM8632 (dual), SGM8633 (single
with shutdown) and SGM8634 (quad) are low noise, low
voltage, and low power operational amplifiers, that can
be designed into a wide range of applications. The
SGM8631/2/3/4 have a high gain-bandwidth product of
6MHz, a slew rate of 3.7V/μs, and a quiescent current of
470μA/amplifier at 5V. The SGM8633 has a power-down
disable feature that reduces the supply current to 90nA.
The SGM8631/2/3/4 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 are 3.5mV for
SGM8631/2/3/4. They are specified over the extended
industrial temperature range (-40 ℃ to +125 ℃ ). The
operating range is from 2.5V to 5.5V.
The SGM8631 single is available in Green SC70-5,
SOT-23-5 and SOIC-8 packages. The SGM8632 dual is
available in Green SOIC-8 and MSOP-8 packages. The
SGM8633 single with shutdown is available in Green
SOT-23-6 and SOIC-8 packages. The SGM8634 quad is
available in Green TSSOP-14 and SOIC-14 packages.
