description  
The OPA688 is a wideband, unity gain stable voltage-feedback op amp that offers bipolar output voltage limiting.  
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 15 mV. The op amp operates linearly to within  
30 mV of the output limit voltages.  
The combination of narrow nonlinear range and low limiting offset allows the limiting voltages to be set within  
100 mV of the desired linear output range. A fast 2.4-ns 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 OPA688 to be used in all standard op  
amp applications.  
Non-linear analog signal processing will benefit from the OPA688s sharp transition from linear operation to  
output limiting. The quick recovery time supports high-speed applications.  
The OPA688M is available in an industry standard pinout CDIP-8 package. For higher gain, or transimpedance  
applications requiring output limiting with fast recovery, consider the OPA689M.
