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°C to +125°C). The
operating range is from 2.5V to 5.5V.
The single version, SGM8631/8633, is available in SC70-5,
SO-8 and SOT23-5(6) packages. The dual version SGM8632
is available in SO-8 and MSOP-8 packages.
