Zero Drift: 0.05µV/oC (Max.) Quiescent Current: 20μA (Typ.) Operating Temperature: -40°C ~ +125°C Available in SOT23-5 and SOP8 Packages
2. General Description
The GT7131 amplifier is single supply, micro-power, zero-drift CMOS operational amplifier, the amplifier offer bandwidth of 350kHz, rail-to-rail inputs and outputs, and single-supply operation from 2.2V to 5.5V. GT7131 uses chopper stabilized technique to provide very low offset voltage (less than 20µV maximum) and near zero drift over temperature.
