Hello!  I have an application where I want to display readings from an RF power amplifier I'm building. Voltage inputs will range from 0-50 millivolts to 0-3 volts.  I purchased a Arduino Mega 2560,an LCD 4.3" captive touch screen, and a 24-bit DAC shield.  I assumed I could stack the DAC between the screen and the Arduino Mega, but that turned out to be physically impossible.  I need the 24 bits to deal with the wide range of input voltages, and differential inputs to handle common mode noise.  How can I make this work?  Once I sort that out my next questions will be to ask if anyone can show me how to display the various amplifier parameters on my screen.
