3 Description
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 nVPP. 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.
