CMOS Operational Amplifiers
PRODUCT DESCRIPTION
FEATURES
The SGM8541 (single), SGM8542 (dual) and SGM8544
(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 SGM8541/2/4 provide 1.1MHz bandwidth at a low
current consumption of 46μA per amplifier. Very low input
bias currents of 0.5pA enable SGM8541/2/4 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.
