Ignacio, The DIE_TEMP difference amp does not use VMID. R362 is not installed, but R367 is. I'm using split tracking supplies for the THS3470, so VMID = 0. Andy

Hi Andy, That might be making a little more sense. The VMID pin is not meant to drive much and can be causing this weird behavior. Our designer was not available today, but I will try to confirm this...
