Q: Find the digital equivalent and the resolution for a 3 bit DAC using Successive Approximation of Vin = 0.4 V and Vref = 1 V?
Without writing or drawing tools to lean on, you must use words, not equations, graphs or schematics in your explanation. The current in a differential pair of transistors swings between the two sides of the transistor pair as the input voltage swings between the inputs. The output voltages of course follow the current inversely. Is this swing of current related to one of the chief advantages of differential operation, the elimination of common mode signals? Keep in mind, there is a restricted range of allowed current (and voltage) swing to keep the amplifier operating in a linear way
