GENERAL DESCRIPTION
The SGM321 (single), SGM358 (dual) and SGM324
(quad) are low cost, rail-to-rail inp ut and output voltag e
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 per 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 the Green SOT-23-5 and
SC70-5 packages. The SGM358 comes in the Green
SOIC-8, MSOP-8 and DIP-8 packages. The SGM324 is
offered in the Green SOIC-14 and TSSOP-14
packages.

OVERSTRESS CAUTION
Stresses beyond those listed may cause permanent damage
to the device. Functional operation of the device at these or
any other
conditions bey ond th ose indic ated in t he operat ional
section
of the
specification
is not implied.
Exposure
to absolute
maximum rating conditions for extended periods may affect
reliability.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged by ESD if you don’t
pay attention to ESD protection. SGMICRO recommends that
all integrate d circuits be handled with appropriate precautions.
Failure
to observe pr op er handling
and installati on proce dures
can cause damage. ESD damage can range from subtle
performance
degradati on to
complete dev ice fai lure. Pre cisio n
integrated circuits may be more susceptible to damage
because very small parametric changes could cause the
device not to meet its publis he d speci fic atio ns.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit
design, spe cificat ion
or o ther related thin gs if necessary
without notice at any time.
