SGM8651/2/4
SGM8653/5
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 2.5 V to 5.5 V.
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 2.3 mA/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°C to +125°C temperature range.

NOTES
1. Stresses above those listed under Absolute Maximum
Ratings may cause permanent damage to the device. This is
a stress rating only; functional operation of the device at
these or any other conditions above those indicated in the
operational section of this specification 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.
Shengbang Micro-electronics 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.
