DESCRIPTION  
function at the output, as opposed to the input, gives the  
specified limiting accuracy for any gain, and allows the  
OPA698 to be used in all standard op amp applications.  
The OPA698 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  
±10mV. The op amp operates linearly to within 20mV of the  
output limit voltages.  
Nonlinear analog signal processing will benefit from the  
ability of the OPA698 to sharply transition from linear opera-  
tion to output limiting. The quick recovery time supports  
high-speed applications.  
The combination of a narrow nonlinear range and the low  
limiting offset allows the limiting voltages to be set within  
100mV of the desired linear output range. A fast 1ns  
recovery from limiting ensures that overdrive signals will be  
transparent to the signal channel. Implementing the limiting  
The OPA698 is available in an industry standard pinout SO-8  
package. For higher gain, or transimpedance applications  
requiring output limiting with fast recovery, consider the  
OPA699.
