SGM8541/2/4
1.1MHz, 46μA, Rail-to-Rail I/O
CMOS Operational Amplifiers
GENERAL DESCRIPTION
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.
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.
The SGM8541 single is available in the Green
SOT-23-5, SC70-5 and SOIC-8 packages. The
SGM8542 dual comes in the Green SOIC-8, MSOP-8
and TSSOP-8 packages. The quad SGM8544 is
offered in Green TSSOP-14 and SOIC-14 packages.
They are specified over the extended industrial
temperature range (-40℃ to +125℃).
