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℃).
