This user's guide describes the characteristics, operation, and use of the ADS8482 18-bit, 1-MHz, parallel interface and ADS8484 18-bit, 1.25-MHz, parallel interface, analog-to-digital converter (ADC) evaluation module (EVM). A complete circuit description, schematic diagram, and bill of materials are included. Throughout this document, the term evaluation module and the abbreviation EVM are synonymous with the ADS848xEVM. For ease of reading, this user's guide refers to the ADS8482EVM or ADS8484EVM as the ADS848xEVM . Operation of the EVM for both devices is identical, unless otherwise noted.
