This chapter shows how to verify the example design towards the desired design goals with the help of both the TINA TI Simulator tool and the ANALOG-ENGINEER’S CALCULATOR. The section also shows how to verify that the signal chain performs to the full differential and common-mode input range of the ADC. Then the total noise performance and the linearity are observed to determine if the ENOB target can be met, followed by a stability analysis and verification of the input impedance. Finally, the chapter provides proof that the circuit meets the settling time requirement of the sample and hold capacitor of the ADC.
