ADS78/ADS8505EVM User's Gu

The ADS7805 and ADS8505 are complete 16-bit analog-to-digital (A/D) using state-of-the-art CMOS  structures. They contain a complete 16-bit, capacitor-based, successive approximation register (SAR) A/D   with sample-and-hold, reference, internal conversion clock, and a parallel data interface with 3-state  output drivers.
The evaluation module (EVM) is available with either the ADS7805 or ADS8505 installed. The EVM can  also accommodate the 12-bit ADS7804 simply removing and replacing the installed device. Samples of   the ADS7804 can be obtained through the sample program at Texas Instruments. See the ADS7804  Product Folder for details.
