GT7132

功能特点

350 kHz, Low Power, Zero-Drift, CMOS, Rail-to-Rail Operational Amplifier with RF Filter

• The GT7131/GT7132 amplifier is single/dual supply,micro-power, zero-drift CMOS operational amplifiers, the amplifiers offer bandwidth of 350 kHz, rail-to-rail inputs and outputs, and single-supply operation from 2.5V to 5.5V. GT7131/GT7132 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 per amplifier 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 GT7131 is available in SOT23-5 and SOP8 packages. And the GT7132 is available in SOP8 and MSOP8 packages. The extended temperature range of -40 o C to +125 o C over all supply voltages offers additional design flexibility.
