Watch this video to get an introduction to Precision DACs. Get a technology overview, then learn about companion products and associated systems.
Lesson 1: Technology Overview
This first lesson provides an overview of the most common technology concepts associated with Precision DACs. Viewers will learn about sampled-data systems, gain an understanding of what a Digital-to-Analog converter (DAC) is, then define the necessary companion products for DACS.
Sampled-Data Systems
“Real-World” sampled-data systems consist of DACs and their counterparts, Analog-to-Digital converters (ADCs). These two precision components are key in the signal chain, and help a system analyze data in the most efficient way.
What is a Digital-to-Analog Converter?
A DAC creates an analog output that corresponds to the relative value of a digital input. A key piece of information here is that the analog output is quantized (discrete step) in response to binary digital input code.
Companion Products
In a DAC system, there needs to be a voltage reference source, an on-chip reference or reference buffer, and a signal amplifier. The specifics of these components can be customized based on the specific output needs of the system.
