SGM8251

GENERAL DESCRIPTION

The single SGM8251 is a rail-to-rail output, low noise and high precision operational amplifier which has low input offset voltage and bias current. It is guaranteed to operate from 4.5V to 36V single supply.

The rail-to-rail output swing provided by the SGM8251 makes both high-side and low-side sensing easy. The combination of these characteristics makes the SGM8251 a good choice 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 SGM8251 is available in Green SOT-23-5, SOIC-8 and MSOP-8 packages. It is rated over the -40 to +125 temperature range.
