OPAx391 Wide Bandwidth RRIO Operational Amplifier

Texas Instruments OPAx391 Wide Bandwidth RRIO Operational Amplifier (Op Amp) features a unique combination of high bandwidth (1MHz) along with a very low quiescent current (24µA) in a high-precision amplifier. These features, combined with rail-to-rail input and output, make this device an exceptional choice in high-gain, low-power applications. The ultra-low input bias current of 10fA, only 45µV of offset (maximum), and 1.2µV/°C of drift over temperature help maintain high precision in ratiometric and amperometric sensor front ends that have demanding low-power requirements.
