Description

This application report discusses how to use a parallel ADC as a serial ADC by using a low-cost CPLD. This concept is tested with a Texas Instruments ADS8411/12 (16-bit 2 MSPS SAR ADC) and an Altera(TM) MAX 3000A CPLD. A full solution with a schematic layout and software for programming the CPLD is presented at the end of the report.
