SGM8049-1/SGM8049-2/SGM8049-4
1.8V, 2.5µA, 120kHz,
Rail-to-Rail I/O Operational Amplifiers
GENERAL DESCRIPTION
The SGM8049-1, SGM8049-2 and SGM8049-4 micro
power, low voltage operational amplifiers are designed
for battery-powered applications. The amplifiers
operate on a supply voltage as low as 1.8V (±0.9V).
High-performance, single-supply operation with railto-rail capability makes the SGM8049-1/2/4 useful for a
wide range of applications.
In addition of small packages, the SGM8049-1/2/4
feature impressive bandwidth, low bias current and low
noise relative to the very low quiescent current.
The single SGM8049-1 is available in Green SC70-5,
SOT-23-5 and TDFN-2×2-6L packages. The dual
SGM8049-2 is available in Green SOT-23-8 and
SOIC-8 packages. The quad SGM8049-4 is available in
Green TSSOP-14 package. They are specified over the
extended -40℃ to +125℃ temperature range.

OVERSTRESS CAUTION
Stresses beyond those listed may cause permanent damage
to the device. Functional operation of the device at these or
any otherconditions beyond those indicated in the operational
section of the specification is not implied.Exposureto 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.
