The OPA383, OPA2383, and OPA4383 (OPAx383) family of precision amplifiers offers state-of-the-art performance. With zero-drift technology, the OPAx383 offset voltage and offset drift provide unparalleled long-term stability. With a ultra-low 65µA of quiescent current, the OPAx383 are able to achieve 2.5MHz of bandwidth, a broadband noise of 32nV/√Hz, and a 1/f noise at 650nVPP. 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 OPAx383 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.
