OPA387 的说明
The OPA387, OPA2387, and OPA4387 ( OPAx387) family of precision amplifiers offers state-of-the-art performance. With zero-drift technology, the OPAx387 offset voltage and offset drift provide unparalleled long-term stability. With a mere 570 µA of quiescent current, the OPAx387 are able to achieve 5.7 MHz of bandwidth, a broadband noise of 8.5 nV/√ Hz, and a 1/f noise at 177 nV PP. These specifications are crucial to achieve extremely-high precision and no degradation of linearity in 16-bit to 24-bit analog to digital converters (ADCs). The OPAx387 feature flat bias current over temperature; 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.
