The SGM8555/6 are rail-to-rail input and output precision operational amplifiers which have low input offset voltage and bias current. They are guaranteed to operate from 2.5V to 5.5V single supply.
The rail-to-rail input and output swings provided by the SGM8555/6 make both high-side and low-side sensing easy. The combination of characteristics makes the SGM8555/6 good choices 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 single SGM8555 is available in Green SOT-23-5, SOIC-8 and MSOP-8 packages. The dual SGM8556 is available in Green SOIC-8 and MSOP-8 packages. They are specified for the extended industrial/automotive (-40℃ to +125℃) temperature range.
