SGM8958-1
Low VOS, Low Noise, High Precision Zero-Drift Operational Amplifier
Low VOS, Low Noise, High Precision Zero-Drift Operational Amplifier
GENERAL DESCRIPTION

The single SGM8958-1 and dual SGM8958-2 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 165μA quiescent current per amplifier. The SGM8958-1/2 support rail-to-rail input and output operation. The input common mode voltage range is 100mV beyond the rails, and the output swings within 5mV of the rails.

The SGM8958-1/2 feature high impedance inputs, a 10μV maximum input offset voltage and zero-drift over time and temperature. These devices are designed to provide optimal performance in low voltage and low power systems. These specifications make the operational amplifiers appropriate for a wide range of applications requiring high precision, such as driving ADCs with high linearity.

The SGM8958-1 is available in Green SOT-23-5, SC70-5 and SOIC-8 packages. The SGM8958-2 is available in Green SOIC-8 and TDFN-3×3-8L packages. They are specified over -40 to +125 temperature range.
