SGM8249-2

GENERAL DESCRIPTION

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

The rail-to-rail output swing provided by the SGM8249-1/2 makes both high-side and low-side sensing easy. The combination of these characteristics makes the SGM8249-1/2 good choices 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 SGM8249-1 is available in Green SOT-23-5 and SOIC-8 packages. The dual SGM8249-2 is available in a Green SOIC-8 package. The SGM8249-1/2 are rated over the -40 to +125 temperature range.
