Product Summary

The ADS7809UB is a complete 16-bit sampling analogto-digital using state-of-the-art CMOS structures. The ADS7809UB 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 ADS7809UB also provides an output synchronization pulse for ease of use with standard DSP processors.
