The SGM8521 (single), SGM8522 (dual) and SGM8524
(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 SGM8521/2/4 provide 150kHz bandwidth at a low
current consumption of 5.5μA per amplifier. Very low
input bias currents enable the SGM8521/2/4 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. SGM8521XN5/TR
