Overview

The OPAx387 family of zero-drift amplifiers is engineered with state-of-the-art, proprietary, precision zero-drift technology. These amplifiers offer ultra-low input offset voltage and drift, and achieve excellent input and output dynamic linearity. The OPAx387 operate from 1.7 V to 5.5 V, are unity-gain stable, and are designed for a wide range of general-purpose and precision applications. The OPAx387 strengths also include a 5.7-MHz bandwidth, 8.5-nV/√Hz noise spectral density, and no 1/f noise, making the OPAx387 an excellent choice for interfacing with sensor modules, and buffering high-fidelity, digital-to-analog converters (DACs).
