Product Summary
The ADS7808U is a complete 12-bit sampling analog-to-digital converter using state-of-the-art CMOS structures. It contains a 12-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 ADS7808U also provides an output synchronization pulse for ease of use with standard DSP processors.
