GENERAL DESCRIPTION
The SGM321 (single), SGM358 (dual) and SGM324
(quad) are low cost, voltage feedback amplifiers. These
devices can operate from 2.1V to 5.5V single supply,
while consuming only 60μA quiescent current per
amplifier. They provide rail-to-rail input with a wide input
common mode voltage range and rail-to-rail output voltage
swing. This feature makes SGM321/358/324 appropriate
for buffering ASIC.
The SGM321/358/324 offer a gain-bandwidth product
of 1MHz and an ultra-low input bias current of 10pA.
They are well suited for piezoelectric sensors, integrators
and photodiode amplifiers.
The SGM321/358/324 are designed
into
a
wide range of
applications, such as battery-powered instrumentation,
safety monitoring, portable systems, and transducer
interface circuits in low power systems.
The SGM321 is available in Green SOT-23-5 and
SC70-5 packages. The SGM358 is available in Green
SOIC-8, MSOP-8 and DIP-8 packages. The SGM324 is
available in Green TSSOP-14 and SOIC-14 packages.
They are specified over the extended industrial
temperature range (-40℃ to +85℃).

OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure
to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section
is not implied.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure
to observe proper handling
and installation procedures
can cause damage. ESD damage can range from subtle
performance
degradation to
complete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
