SGM8922
12.7MHz, Dual Rail-to-Rail
Output Operational Amplifier
PRODUCT DESCRIPTION
The SGM8922 is a dual, rail-to-rail output operational
amplifier that is optimized and fully specified for 5V
operation.
High
output
current
allows
low
load
impedances to be driven.
The SGM8922 has a wide input common mode voltage
range and output voltage swing, running at single supply
voltage from 3V to 5.5V.
The SGM8922 provides excellent overall performance. It
exhibits low noise, distortion, low offset and high output
current capability, making this device an excellent choice
for high quality, low voltage or battery operated audio
systems.
The SGM8922 is offered in Green MSOP-8, TSSOP-8
and SOIC-8 packages and ESD (HBM) reaches 8kV. It is
specified over the extended -40℃ to +125℃
temperature range.

NOTE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
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.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get
the latest datasheet.
