SGM8255A-1XN5G/TR

The single-channel SGM8255A-1 and dual-channel SGM8255A-2 are rail-to-rail output, low-noise, high-precision op-amps with 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 high-side and low-side sensing straightforward. This combination of features makes the SGM8255A-1/2 ideal for temperature, position, and pressure sensors, medical equipment, strain gauge amplifiers, or any other 4.5V to 36V application requiring precision and long-term stability. The single-channel SGM8255A-1 is available in green SOT-23-5, SOIC-8, and MSOP-8 packages. The dual-channel SGM8255A-2 is available in green SOIC-8 and MSOP-8 packages. The SGM8255A-1/2 operates over a temperature range of -40°C to +125°C.
