GENERAL DESCRIPTION
The AD679 is a plete, multipurpose 14-bit monolithic analog-to-digital converter, consisting of a sample-and-hold amplifier (SHA), a microprocessor-patible bus interface, a voltage reference, and clock generation circuitry.
The AD679 is specified for ac (or dynamic) parameters such as S/N+D ratio, THD, and IMD, which are important in signal processing applications. In addition, the AD679K, B, and T grades are fully specified for dc parameters that are...
