Product Summary
The ADS7809 is a complete 16-bit sampling analogto-digital using state-of-the-art CMOS structures. It contains a 16-bit capacitor-based SAR A/D with S/H, reference, clock, and a serial data interface. Data can be output using the internal clock, or can be synchronized to an external data clock. The ADS7809 also provides an output synchronization pulse for ease of use with standard DSP processors.
