The SGM8531 (single), SGM8532 (dual) and SGM8534
(quad) are low cost, rail-to-rail input and output voltage
feedback amplifiers. They have a wide input common
mode voltage range and output voltage swing, and take
the minimum operating supply voltage down to 2.1V. The
maximum recommended supply voltage is 5.5V. All are
specified over the extended -40℃ to +125℃ temperature
range.
The SGM8531/2/4 provide 500kHz bandwidth at a low
current consumption of 18μA per amplifier. Very low input
bias currents of 0.5pA enable the SGM8531/2/4 to be
used for integrators, photodiode amplifiers, and
piezoelectric sensors. Rail-to-rail input and output are
useful to designers for buffering ASIC in single-supply
systems.
Applications for these amplifiers include safety monitoring,
portable equipment, battery and power supply control,
and signal conditioning and interfacing for transducers in
very low power systems. SGM8531XN5/TR
