DESCRIPON

The ADS8519 is a complete 16-bit sampling analog-to-digital A/D converter using state-of-the-art CMOS structures. It contains a complete 16-bit, capacitor-based, successive approximation register  SAR A/D converter with sample-and-hold, reference, clock, and a serial data interface. Data can be output using the internal clock or synchronized to an external data clock. The ADS8519 also provides an output synchronization pulse for ease-of-use with standard DSP processors.
