The single SGM8249-1 and dual SGM8249-2 are high voltage, low noise and high precision operational amplifiers which can operate from 4.5V to 36V single supply or from ±2.25V to ±18V dual supplies. These devices provide rail-to-rail output operation.

The SGM8249-1/2 offer a low offset voltage less than 10μV and a low bias current. The combination of characteristics makes the SGM8249-1/2 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 SGM8249-1 is available in Green SOT-23-5 and SOIC-8 packages. The SGM8249-2 is available in a Green SOIC-8 package. The SGM8249-1/2 are rated over the -40 to +125 temperature range.
