The single SGM8255A-1 and dual SGM8255A-2 are low noise and high precision operational amplifiers optimized for high voltage operation from 4.5V to 36V single supply. These devices provide rail-to-rail output operation.
The SGM8255A-1/2 offer a low offset voltage less than 25μV and a low bias current. The combination of characteristics makes the SGM8255A-1/2 good choices for temperature measurements, pressure and position sensors, strain gauge amplifiers and medical instrumentation, or any other 4.5V to 36V applications requiring precision and long-term stability.
The SGM8255A-1 is available in Green SOT-23-5, SOIC-8 and MSOP-8 packages. The 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.
