GT7131

功能特点

350kHz, Zero-Drift, CMOS,Rail-to-Rail Operational Amplifier

• 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 applications. The single GT7131 is available in space-saving, SOT23-5 and SOP-8 package. The extended temperature range of -40 o C to +125 o C over all supply voltages offers additional design flexibility.
