SGM8256-1_SGM8256-2_SGM8256-4.pdf

The SGM8256-1/2/4 are a family of single, dual and quad operational amplifiers, which are optimized for low noise, high precision and high voltage operation. These devices can operate from 4.5V to 36V single supply. They provide rail-to-rail input and output operation.

The SGM8256-1/2/4 offer a low offset voltage of ±18μV (MAX) and a low bias current. The combination of characteristics makes them good choices for temperature measurements, pressure and position sensors, strain gauge amplifiers and medical instrumentation, or any other 4.5V to 36V applications requiring precision, long-term stability and low drifting.

The SGM8256-1 is available in Green SOT-23-5 and SOIC-8 packages. The SGM8256-2 is available in Green SOIC-8 and MSOP-8 packages. The SGM8256-4 is available in Green SOIC-14 and TSSOP-14 packages. They are rated over the -40℃ to +125℃ temperature range.
