PRODUCT DESCRIPTION
The SGM8531 (single)，SGM8532 (dual) and SGM8534
(quad) are rail-to-rail input and output voltage feedback
amplifiers offering low cost. They have a wide input
common-mode voltage range and output voltage swing,
and
take the minimum operating supply voltage down to
2.1V and the maximum recommended supply voltage is
5.5 V.
All are specified over the extended –40°C to
+125°C temperature range.
The SGM8531/8532/8534 provide 500KHz bandwidth at a
low current consumption of 18µA per amplifier. Very
low input bias currents of 0.5 pA, enable the
SGM8531/8532/8534 to be used for integrators,
photodiode amplifiers, and piezoelectric sensors.
Rail-to-Rail inputs and outputs are useful to designers
buffering ASIC in single-supply systems.
Applications for these amplifiers include safety monitor-
ing, portable equipment, battery and power supply
control, and signal conditioning and interfacing for
transducers in very low power systems.
The SGM8531 is available in the tiny SOT23-5 and SO-8
packages. The SGM8532 comes in the miniature SO-8 and
MSOP-8 packages. The SGM8534 is offered in TSSOP-14,
TSSOP-16, SO-14 and SO-16 packages.

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.
