SGM8038-1/SGM8038-2
6µA, 145kHz, Rail-to-Rail I/O,
High Precision Operational Amplifiers
GENERAL DESCRIPTION
FEATURES
The single SGM8038-1 and dual SGM8038-2 are high
precision operational amplifiers which can operate from
1.4V to 5.5V single supply, while consuming only 6µA
quiescent current per amplifier. They are capable of
rail-to-rail input and output. Therefore, the SGM8038-1/2
are suitable for use in portable instrumentation and
battery-powered equipment.
● Low Quiescent Current: 6µA/Amplifier (TYP)
● Low Offset Voltage: 800µV (MAX) at VS = 5V
● Unity-Gain Stable
● Gain-Bandwidth Product: 145kHz (TYP) at VS = 5V
● Rail-to-Rail Input and Output
● Supply Voltage Range: 1.4V to 5.5V
● -40℃ to +125℃ Operating Temperature Range
● Small Packaging:
The SGM8038-1/2 are unity-gain stable, and feature a
145kHz gain-bandwidth product. They are designed to
provide optimal performance in low-frequency systems,
when monitoring battery current and conditioning sensor
signal.
SGM8038-1 Available in Green SOT-23-5, SC70-5
and SOIC-8 Packages
SGM8038-2 Available in Green SOT-23-8, SOIC-8
and TDFN-2×2-8L Packages
The SGM8038-1 is available in Green SOT-23-5,
SC70-5 and SOIC-8 packages. The SGM8038-2 is
available in Green SOT-23-8, SOIC-8 and TDFN-2×2-8L
packages. They operate over an ambient temperature
range of -40℃ to +125℃.

ESD Susceptibility
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

DISCLAIMER
SG Micro Corp reserves the right to make any change in
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
