SGM8582 Single-Supply, Dual Rail-to-Rail I/O Precision Operational Amplifier

GENERAL DESCRIPTION

The SGM8582 is a dual 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 SGM8582 make both high-side and low-side sensing easy. The combination of characteristics makes the SGM8582 good choices for temperature, position and pressure sensors, medical equipment and strain gauge amplifiers, or any other 2.5V to 5.5V application requiring precision and long term stability.

The SGM8582 is specified for the extended industrial/automotive (-40 to +125) temperature range. The SGM8582 comes in the Green SOIC-8 and MSOP-8 packages.
