The SGM8249-4 is a quad, high voltage, low noise and high precision operational amplifier which can operate from 4.5V to 36V single supply or from ±2.25V to ±18V dual supplies. The device provides rail-to-rail output operation.

The SGM8249-4 offers a low offset voltage less than 12μV and a low bias current. The combination of characteristics makes the SGM8249-4 a good choice 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 SGM8249-4 is available in Green SOIC-14 and TSSOP-14 packages. It is specified over the extended -40℃ to +125℃ temperature range.
