SGM8521/2/4
150kHz, 5.5μA, Rail-to-Rail I/O
CMOS Operational Amplifiers
GENERAL DESCRIPTION
FEATURES
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.
The SGM8521 single is available in Green SOT-23-5
and SOIC-8 packages. The SGM8522 dual comes in
Green SOIC-8 and MSOP-8 packages. The SGM8524
quad is offered in Green SOIC-14 and TSSOP-14
packages.
