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.
