SGM8048
690nA, Non-Unity Gain, Quad Rail-to-Rail
Input/Output Operational Amplifier
PRODUCT DESCRIPTION
The SGM8048 operates with a single supply voltage as
low as 1.4V, while drawing less than 690nA (TYP) of
quiescent current per amplifier. This device is also
designed to support rail-to-rail input and output operation.
This combination of features supports battery-powered
and portable applications.
The SGM8048 has a gain-bandwidth product of 100kHz
(TYP) and is stable for gains
≥
10. The combination of
characteristics makes the SGM8048 ideal for low
frequency applications, such as battery current
monitoring and sensor conditioning.
The SGM8048 operational amplifier is offered in quad
configuration and it is specified for the extended industrial
(-40℃ to +85℃) temperature range. The SGM8048 is
available in the Green SOIC-14, TSSOP-14 packages.

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.
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.
