SGM2324
PRODUCT DESCRIPTION
The SGM2324 has quad 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 5.5V. SGM2324 is
specified over the extended -40°C to +85°C temperature
range.
The amplifier in SGM2324 provides 1MHz bandwidth;
very low input bias currents of 10pA, these features
enable SGM2324 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 SGM2324 include safety monitoring,
portable equipment, battery and power supply control,
signal conditioning and interfacing for transducers in low
power systems.
The SGM2324 is offered in SO-16, TSSOP-16, TSSOP-14
and SO-14 packages.

CAUTION
This integrated circuit can be damaged by ESD. SG
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.
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.
