This article introduces the design guidelines for the SAR ADC front-end driver and RC filter, then introduces the SAR ADC design of ADI's new generation high-impedance input front-end, and then uses LTspice simulation to verify the comparison between high-impedance input and traditional input modes. This input high-impedance technology simplifies driver design, broadens the selection of ADC drivers, reduces the power consumption and size of the overall signal chain, and thereby helps solve the system-level technical challenges of precision data acquisition systems.
