    Hi I am working on a design which has  LT6106 current sense amplifier where the VCC is 5V and IN+ and IN- is 12V. Device is working now and I want to understand if the internal ESD structure of the IC are specialised enough for this application as when Input voltage is higher than the supply voltage.  If not can i have a drop in replacement of that IC which are having such capability as i cant change the design now. opamp

      Hi Shenoy, 
      
 
      Are you still talking about the LT6106?
      
 
      If so, and the IN+ and IN- pins were set to voltages outside of the supply, there is a high likelihood that the amplifier was damaged because the absolute maximum ratings were violated. 
      
 
      If you're able to check the supply current to see if it is still within spec, that would be a good indication of whether the part is really still good or not. 
      
 
      Thanks,
