SGM8651/2/4
SGM8653/5
50MHz, Rail-to-Rail Output
CMOS Operational Amplifiers
PRODUCT DESCRIPTION
The SGM8651/2/3/4/5 are high precision, low noise, low
distortion, rail-to-rail output CMOS voltage feedback
operational amplifiers offering ease of use and low cost.
They have a wide input common mode voltage range and
output voltage swing, running at single-supply voltage
from 2.5V to 5.5V.
Despite being low cost, the SGM8651/2/3/4/5 provide
excellent overall performance. They offer wide gain-
bandwidth product to 50MHz and a typical low power of
2.3mA/amplifier.
The SGM8651/2/3/4/5‘s low distortion and fast settling
make them ideal for buffering high speed A/D or D/A
converters. The SGM8653/5 has a power-down disable
feature that reduces the supply current to 75μA/amplifier.
These features make the SGM8653/5 ideal for portable
and battery-powered applications where size and power
are critical. All are 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.
