PRODUCT DESCRIPTION
The SGM8521 (single)，SGM8522 (dual) and SGM8524
(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 SGM8521/8522/8524 provide150KHz bandwidth at a
low current consumption of 4.7µA per amplifier. Very
low input bias currents of 0.5pA, enable the
SGM8521/8522/8524 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 SGM8521 is available in the tiny SOT23-5 and SO-8
packages. The SGM8522 comes in the miniature SO-8 and
MSOP-8 packages. The SGM8524 is offered in TSSOP-16
SO-16 and SO-14 packages.
