In talking to system designers using analog-to-digital converters (ADCs), one of the most common questions that I hear is:
“Is your 16-bit ADC also 16-bit accurate?”
The answer to this…

In the first ADC Accuracy post, we established the differences between the resolution and accuracy for an analog-to-digital converter (ADC). Now we can dig into the factors that contribute toward total…
“A clever person solves a problem. A wise person avoids it.” – Albert Einstein
Albert Einstein would have loved analog design – there is always an element of relativity involved. For example, in data acquisition systems, accuracy is relative…

Did you know that the input signal might affect how you select the best successive approximation register (SAR) analog-to-digital converter (ADC) for your application?
When we hear the word, “input…
This is the second post in our SAR ADC series.
Part 2: A marketing analogy
When a response time of 1 µs is required from the SAR ADC (tRESP-ADC = 1 µs), many engineers would search for a SAR ADC with throughput of 1 Msps (tTHROUGHPUT = 1 us…

Part 1:
The objective of many typical control system applications is to effect a control action based on the status of input control variables. Some of these include position, speed, angle, level, temperature…
