SGM8521/2/4
150kHz, 5.5μA, Rail-to-Rail I/O
CMOS Operational Amplifiers
GENERAL DESCRIPTION
The
SGM8521
(single),
SGM8522
(dual)
and
SGM8524 (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 +125℃ temperature range.
The SGM8521/2/4 provide 150kHz bandwidth at a low
current consumption of 5.5μA per amplifier. Very low
input bias currents enable the SGM8521/2/4 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
these
amplifiers
include

ABSOLUTE MAXIMUM RATINGS
OVERSTRESS CAUTION
Stresses beyond those listed may cause permanent damage
to the device. Functional operation of the device at these or
any other conditions beyond those indicated in the operational
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 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.
RECOMMENDED OPERATING CONDITIONS
Operating Temperature Range ..................... -40℃ to +125℃
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, specification or other related things if necessary
without notice at any time.
