This reference design, provided by Dallas Logic Corp, uses the ADC34J22 12b 50MSPS JESD204B data converter and the THS4541 fully differential amplifier to show how to design a high-performance active interface for high speed ADCs. This type of circuit can be used in sensor front end, motor control, and test and measurement applications. The circuit model and derivation of the design equations is presented along with the actual implementation on a PCB. Results of this implementation are presented to show very similar performance as compared to a passive AC coupled transformer interface.
