DESCRIPTION  
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.  
The OPA689 is a wideband, voltage feedback op amp  
that offers bipolar output voltage limiting, and is stable  
for gains ≥ +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.  
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 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  
The OPA689 is available in an industry-standard pinout  
in PDIP-8 and SO-8 packages. For lower gain applica-  
tions requiring output limiting with fast recovery, con-  
sider the OPA688.
