The OPA689 is a wideband, voltage feedback op amp
that offers bipolar output voltage limiting, and is stable
for gains ³ +4. Two buffered limiting voltages take
control of the output when it attempts to drive beyond
these limits. This new output limiting architecture holds
the limiter offset error to ±15mV. The op amp operates
linearly to within 30mV of the limits.
The combination of narrow nonlinear range and low
limiting offset allows the limiting voltages to be set within
100mV of the desired linear output range. A fast 2.4ns
recovery from limiting ensures that overdrive signals will
be transparent to the signal channel. Implementing the
limiting function at the output, as opposed to the input,
gives the specified limiting accuracy for any gain, and
allows the OPA689 to be used in all standard op amp
applications.
Non-linear analog signal processing circuits will benefit
from the OPA689’s sharp transition from linear operation
to output limiting. The quick recovery time supports high
speed applications.
The OPA689 is available in an industry-standard pinout
in PDIP-8 and SO-8 packages. For lower gain applications
requiring output limiting with fast recovery, consider
the OPA688.
