GENERAL DEscriptION

The single SGM8955 and dual SGM8956 are low power, high precision CMOS operational amplifiers, which can operate from 1.8V to 5.5V single supply or from ±0.9V to ±2.75V dual power supplies, while consuming only 20μA current per amplifier. The SGM8955/6 support rail-to-rail input and output operation. The input common mode voltage range is from (-VS) - 0.1V to (+VS) + 0.1V, and the output range is from (-VS) + 0.014V to (+VS) - 0.014V.

The SGM8955/6 are designed to provide optimal performance in low voltage and low power systems. They have high impedance inputs and zero-drift 50μV (MAX) offset voltage. These specifications make SGM8955/6 appropriate for a wide range of applications re high precision, such as high linearity driver of high precision ADC.

The SGM8955 is available in Green SOT-23-5, SC70-5 and SOIC-8 packages. The SGM8956 is available in Green SOIC-8, MSOP-8 and TDFN-3×3-8L packages. They are specified over -40℃ to +125℃ temperature range.
