The SGM8551 is a single, precision operational amplifier which can operate from 2.5V to 5.5V single supply. The device provides rail-to-rail input and output operation.
The SGM8551 offers a low offset voltage less than 20μV and an ultra-low bias current of 10pA. The combination of characteristics makes the SGM8551 a good choice for temperature measurements, pressure and position sensors, strain gauge amplifiers and medical instrumentation, or any other 2.5V to 5.5V applications requiring precision and long-term stability.
The SGM8551 is available in Green SOIC-8 and MSOP-8 packages. It is specified over the extended industrial temperature range (-40℃ to +125℃).
