CTSD Precision ADCs (Part 1): Improving Signal-Chain Design Time (Download)

Read this article online.

In many digital processing applications and algorithms, the demand to have better resolution and precision for all converter technologies has increased over the last two decades. The limited resolution/precision of analog-to-digital converters (ADCs) was enhanced by using an external digital controller that would extract and deliver more precise results using software techniques such as averaging and optimized filtering schemes.

To reduce extensive postprocessing at the digital microcontroller or DSP, designers could use a high-performance precision ADC. This would reduce optimization time at the digital side, and a lower-cost microcontroller or DSP also could be considered.
