The SGM8252A 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 SGM8252A offers a low offset voltage less than 18μV and a low bias current. The combination of characteristics makes the SGM8252A 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 SGM8252A is available in Green SOIC-8 and MSOP-8 packages. It is rated over the -40℃ to +125℃ temperature range.
