ADS5421/ADS5422EVM User’s Gui

The ADS5421/22 evaluation module is designed for ease of use when  evaluating the high-speed, analog-to-digital converters (ADCs) ADS5421 and  ADS5422. Both converters offer 14 bits of resolution with sampling rates of up  to 40MSPS for the ADS5421 and up to 62MSPS for the ADS5422. This EVM  features two independant sections: one is configured for ac input coupling  using a transformer; the other allows for dc-coupling by employing a  differential amplifier. Each section is completely assembled and operational,  featuring a dedicated layout; no reconfiguration by the user is needed. The  data output of the ADS5421/22 converter is decoupled from the connector by  a CMOS logic buffer.
