SGM8255B-2XS8G/TR

The SGM8255B-2 is a dual, low-noise, high-precision op amp optimized for high-voltage operation from a 4.5V to 36V single supply. The device provides rail-to-rail output operation. The SGM8255B-2 features an offset voltage below 25μV and low bias current. This combination of characteristics makes the SGM8255B-2 an ideal choice for temperature measurement, pressure and position sensors, strain gauge amplifiers, medical instrumentation, or any other 4.5V to 36V application requiring precision and long-term stability. The SGM8255B-2 is available in green SOIC-8 and MSOP-8 packages, with an operating temperature range of -40°C to +125°C.
