SGM8925/SGM8927
110kHz, 6.4μA, Rail-to-Rail Output
CMOS Operational Amplifiers
GENERAL DESCRIPTION
FEATURES
The SGM8925 (single) and SGM8927 (single with
shutdown) are low offset voltage, low power, voltage
feedback amplifiers. These devices can operate from
1.6V to 5.5V single supply, while consuming only 6.4μA
quiescent current. They provide a wide input common
mode voltage range and rail-to-rail output voltage swing.
This feature makes SGM8925/7 appropriate for buffering
ASIC.
● Low Offset Voltage: 0.6mV (MAX)
● Unity-Gain Stable
● Gain-Bandwidth Product: 110kHz
● Rail-to-Rail Output
● Supply Voltage Range: 1.6V to 5.5V
● Low Supply Current: 6.4μA (TYP)
● -40℃ to +85℃ Operating Temperature Range
● Small Packaging:
SGM8925 Available in Green SOT-23-5, SC70-5,
SOIC-8 and MSOP-8 Packages
The SGM8925/7 offer a gain-bandwidth product of
100kHz and an ultra-low input bias current of 1pA. They
are well suited for piezoelectric sensors, integrators and
photodiode amplifiers.
SGM8927 Available in Green SOT-23-6, SOIC-8
and MSOP-8 Packages
The SGM8925/7 are designed into a wide range of
applications, such as battery-powered instrumentation,
safety monitoring, portable systems, and transducer
interface circuits in low power systems.
APPLICATIONS
ASIC Input or Output Amplifiers
Piezoelectric Transducer Amplifiers
Battery-Powered Equipment
Portable Equipment
Sensor Interfaces
The SGM8925 is available in Green SOT-23-5, SC70-5,
MSOP-8 and SOIC-8 packages. The SGM8927 is
available in Green SOT-23-6, MSOP-8 and SOIC-8
packages. They are specified over the extended -40℃
to +85℃ temperature range.

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.
