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, a slew rate of 1.7V/µs, and a quiescent current of
250µA/amplifier at 5V. The SGM8623 has a power-down
disable feature that reduces the supply current to
150nA.
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°C to +125°C). The
operating range is from 2.5V to 5.5V.
The single version, SGM8621/8623, is available in SC70-5,
SO-8 and SOT23-5(6) packages. The dual version
SGM8622 is available in SO-8 and MSOP-8 packages.
The quad version SGM8624 is available in SO-16 and
TSSOP-16 packages.
