INTRODUCTION
Large systems are comprised of many different subsystems, all of
which must interface to complete the system. All types of circuits,
including linear, digital and discrete, are often used in the
subsystems.
Interface circuits provide the necessary function of tying the parts of
a system together. These circuits are usually not purely linear or
digital but contain both types of circuit functions. For instance, sense
amplifiers are designed for interface between low level memory
outputs and bipolar levels, while differential comparators are
designed for interface between analog systems and logic systems.

CONVERTERS
Digital communications, digital instruments and displays
have created a demand for low cost reliable converters. Key
factors in this demand are:
The need to communicate with digital computers and equipment
for processing and storage of analog signals.
Severe limitations encountered in reliable analog data
transmission over any considerable distance.
The need for more easily readable displays.
General application areas for converters include: Data processing,
data transmission, graphics and displays, audio systems, control
systems and arithmetic operations.
