• 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. •
