1.5 MHz, Zero-Drift, CMOS, Rail-to-Rail Operational Amplifier with RF Filter
• The GT7161/GT7162 amplifier is single/dual supply,micro-power, zero-drift CMOS operational amplifiers, the amplifiers offer bandwidth of 1.5 MHz, rail-to-rail inputs and outputs, and single-supply operation from 2.5V to 5.5V. GT7161/GT7162 uses chopper stabilized technique to provide very low offset voltage (less than 10µV maximum) and near zero drift over temperature. Low quiescent supply current of 320μA 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 GT7161 is available in SOT23-5 and SOP8 packages. And the GT7162 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.
