1 Introduction
The ADS8344 and ADS8345 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, external reference, and a serial data interface. Programmable options allow the use
of an internal oscillator or the external serial clock as the conversion clock source.
The EVM is available with either the ADS8344 and ADS8345 installed. The EVM can accommodate the
12-bit ADS7844 by simply removing and replacing the installed device. Samples of the ADS7844 can be
obtained through the sample program at Texas Instruments. See the ADS7844 Product Folder for details.
