SGM2358
1MHz, General Purpose
CMOS Operational Amplifier
PRODUCT DESCRIPTION
The SGM2358 has dual rail-to-rail output voltage
feedback amplifiers in one package. It takes the
minimum operating supply voltage down to 3V and
the maximum recommended supply voltage is 5.5 V.
www.DataSheSeGt4UM.c2o3m58 is specified over the extended -40°C to +85°C
temperature range.
The amplifier in SGM2358 provides 1MHz bandwidth,
Very low input bias currents of 10pA, these features
enable SGM2358 to be used for integrators, photodiode
amplifiers, and piezoelectric sensors. Rail-to-rail output
feature is useful for designers to buffer ASIC in
single-supply systems.
Applications of SGM2358 include safety monitoring,
portable equipment, battery and power supply control,
signal conditioning and interfacing for transducers in
low power systems.
The SGM2358 comes in SO-8 package.

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.
