FEATURES
PRODUCT DESCRIPTION
y Low Cost
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
y Rail-to-Rail Input and Output
0.8mV Typical VOS
y High Gain-Bandwidth Product: 6MHz
y High Slew Rate: 3.7V/µs
y Settling Time to 0.1% with 2V Step: 2.1µs
y Overload Recovery Time: 0.9µs
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.
y Low Noise : 12 nV/
Hz
y Operates on 2.5 V to 5.5V Supplies
y Input Voltage Range = - 0.1 V to +5.6 V with VS = 5.5 V
y Low Power
470μA/Amplifier Typical Supply Current
SGM8633 90nA when Disabled
y Small Packaging
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.
SGM8631 Available in SC70-5, SOT23-5 and SO-8
SGM8632 Available in MSOP-8 and SO-8
SGM8633 Available in SOT23-6 and SO-8
SGM8634 Available in TSSOP-16 and SO-16
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. The quad
version SGM8634 is available in SO-16 and TSSOP-16
packages.
