GENERAL DESCRIPTION
The SGM321 (single), SGM358 (dual) and SGM324
(quad) are low cost, rail-to-rail input and output voltage
feedback amplifiers. They have a wide input common
mode voltage range and output voltage swing, and take
the minimum operating supply voltage down to 2.1V.
The maximum recommended supply voltage is 5.5V.
All are specified over the extended -40℃ to +85℃
temperature range.
The SGM321/358/324 provide 1MHz bandwidth at a
low current consumption of 60μA/amplifier. Very low
input
bias currents of
10pA
enable SGM321/358/324 to
be used for integrators, photodiode amplifiers and
piezoelectric sensors. Rail-to-rail input and output are
useful to designers for buffering ASIC in single-supply
systems.
Applications for this series of amplifiers include safety
monitoring, portable equipment, battery and power
supply control, and signal conditioning and interfacing
for transducers in very 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 SOIC-14 and TSSOP-14 packages.

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 by ESD if you don’t
pay attention to ESD protection. 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 very small parametric changes could cause the
device not to meet its published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit
design, or specifications
without prior notice.
