SGM8634
470μA, 6MHz, Rail-to-Rail I/O
CMOS Operational Amplifier
PRODUCT DESCRIPTION
The quad SGM8634 is a low noise, low voltage, and low
power operational amplifier that can be designed into a
wide range of applications. The SGM8634 has a high
gain-bandwidth product of 6MHz, a slew rate of 3.7V/μs,
and a quiescent current of 470μA/amplifier at 5V.
The
SGM8634
is
designed
to
provide

OS
performance in low voltage and low noise systems. It
provides rail-to-rail output swing into heavy loads. The
input common mode voltage range includes ground,
and the maximum input offset voltage is 3.5mV. The
operating range is from 2.5V to 5.5V.
The quad SGM8634 is available in Green TSSOP-14
and SOIC-14 packages. It is specified over the extended
industrial temperature range (-40℃ to +125℃).

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.
