[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 ...

When it comes to getting signals from an analog world into our computers, most of us don’t give much thought to how the hardware that does the job works. But as it turns out, there are a number of ...

A successive approximation register analog-to-digital converter (SAR ADC) with a switched-capacitor programmable gain switched preamplifier (SC PGSA), as a basic component of an integrated ultra-low ...

At the International Solid-State Circuits Conference in San Francisco, Analog Devices revealed a 20-bit 1Msample/s successive approximation ADC with 0.3ppm INL (integral non‑linearity). Key to this ...

The three most popular ADC types generally found in analog front ends are successive-approximation (a), pipelined (b), and delta-sigma (c). These block diagrams represent extremely simplified concepts ...

Editor's note: We will publish this article in four sequential parts leading up to our “Ask the experts” session on Precision Voltage References on May 21. Alan Walsh will be one of our experts. The ...

Low cost microcontrollers are increasingly expected to provide high performance analog functions for applications that previously used stand-alone ADCs. These applications include power metering, ...

Linear Technology introduces the LTC2311-16, a 16-bit, 5Msps successive approximation register analog-to-digital converter with a wide rail-to-rail input common mode range. Instrumentation and medical ...
