8.5MHz, High Voltage, High Precision, Low Noise, Operational Amplifier
GENERAL DESCRIPTION

The SGM8255B-2 is a dual, low noise and high precision operational amplifier optimized for high voltage operation from 4.5V to 36V single supply. The device provides rail-to-rail output operation.

The SGM8255B-2 offers a low offset voltage less than 25μV and a low bias current. The combination of characteristics makes the SGM8255B-2 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 SGM8255B-2 is available in Green SOIC-8 and MSOP-8 packages. It is rated over the -40 to +125 temperature range.
