OPAx387 Precision Zero-Drift Op Amps

Texas Instruments OPAx387 Precision Zero-Drift Operational Amplifiers (Op Amps) comes with zero-drift technology, provides an offset voltage and offset drift that gives unparalleled long-term stability. With a mere 570µA of quiescent current, the OPAx387 can achieve 5.7MHz of bandwidth, a broadband noise of 8.5 V/√Hz, and a 1/f noise, at 177nVPP. These specifications are crucial to achieving extremely-high precision and no degradation of linearity in 16-bit to 24-bit analog to digital converters (ADCs). The Texas Instruments OPAx387 features a flat bias current over-temperature, and therefore, little to no calibration is needed in high input impedance applications over temperature. All versions are specified over the industrial temperature range of –40°C to +125°C.
