My customer adopt AMC7832 solution. In fact, they need to support negative DAC voltage range to about -5V. AVEE is connedted to -7V, VRANGEA is connected to 2.5V. But they do a wrong connection for AVSSA, AVSSA is connected to GND. Is it ok to support negative DAC voltage with AVSSa connected to GND or must connect AVSSA to AVEE? Thanks a lot!
