          SGM8255A-2

          GENERAL DESCRIPTION

          The single SGM8255A-1 and dual SGM8255A-2 are rail-to-rail output, low noise and high precision operational amplifiers which have low input offset voltage and bias current. They are guaranteed to operate from 4.5V to 36V single supply.

          The rail-to-rail output swing provided by the SGM8255A-1/2 makes both high-side and low-side sensing easy. The combination of these characteristics makes the SGM8255A-1/2 good choices for temperature, position and pressure sensors, medical equipment and strain gauge amplifiers, or any other 4.5V to 36V applications requiring precision and long term stability.

          The single SGM8255A-1 is available in Green SOT-23-5, SOIC-8 and MSOP-8 packages. The dual SGM8255A-2 is available in Green SOIC-8 and MSOP-8 packages. The SGM8255A-1/2 are rated over the -40 to +125 temperature range.
