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 a

Hi Krisf,

Meanwhile on one of the board I tried connecting 12V on the VCC pin isolating the 5V rail. Now the VIN+, VIN- and VCC are at 12V. I should be getting in the range of .8V output. While simulating in Spice I got around 0.7V but I am getting around 3.2V on the VOUT pin when I probed on board. Maximum Voltage swing on that pin is 1.4V as per datasheet. So little confused on how it is producing 3.2V after correcting the VCC. Is it because device is already gone bad due to initial conditions? Have you faced something similar ?

Thanks
