successive approximation

[Igor] made a VU meter with LEDs using 8 LEDs and 8 comparators. This is a fast way to get one of 8 bits to indicate an input voltage, but that’s only the equivalent of a 3-bit analog to digital ...

“Golden Gloves” A/D Converter Match, Round 2: Successive-approximation register vs. sigma-delta topology–Power Efficiency

After the seven-round fight back in April 2010 between the successive-approximation register (SAR) analog/digital converter (ADC) and the sigma-delta (S?) ADC, Figure 1, (click here to see the full ...

Successive-Approximation Register ADCs Sample To 800 ksamples/s

Three additions to the PulSAR family of successive-approximation register (SAR) analog-to-digital converters (ADCs) offer sampling rates of 800 ksamples/s (AD7674), 100 ksamples/s (AD7678), and 570 ...

What’s the Difference Between SAR and Delta-Sigma ADCs?

This file type includes high-resolution graphics and schematics when applicable. Today, almost every electronic product contains an analog-to-digital converter (ADC). When designing a new product, one ...
