    SGM8581

    GENERAL DESCRIPTION

    The SGM8581 is a single rail-to-rail input and output precision operational amplifier which has low input offset voltage and bias current. It is guaranteed to operate from 2.5V to 5.5V single supply.

    The rail-to-rail input and output swings provided by the SGM8581 make both high-side and low-side sensing easy. The combination of characteristics makes the SGM8581 a good choice for temperature, position and pressure sensors, medical equipment and strain gauge amplifiers, or any other 2.5V to 5.5V applications requiring precision and long term stability.

    The SGM8581 is specified for the extended industrial/automotive (-40 to +125) temperature range. The SGM8581 is available in Green SOT-23-5, SOIC-8 and MSOP-8 packages.
