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. Low quiescent supply current of 20μA and very low input bias current of 10pA make the devices an ideal choice for low offset, low power consumption and high impedance applica...
