Op amps are the fundamental building blocks of analog circuits; you can build all analog functions from op amps. Add digital output circuitry to an op amp to get a comparator that can also function as ...

Editor’s note: Here’s an oldie but goodie. EDN editors regularly field requests for copies of articles that predate our online archive, but this Design Idea from our Feb 20, 1986, issue has generated ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

Analog Devices has announced what it claims to be the industry's first precision instrumentation amplifier designed and manufactured specifically for high temperature applications. According to the ...

An instrumentation amplifier with ultra low noise, low power and low distortion has been introduced by Analog Devices. The AD8429 is designed for the precise measurement of small signals present in ...

When something is described as “Low Noise”, it is by the nature of the language a relative phrase. The higest quality magnetic tape is low noise compared to its cheaper sibling for example, but still ...

Figure 1 shows a benign means of interfacing a low-level, wideband differential signal to an analog-to-digital converter (ADC). The FET input stage (AD8066) draws only 6 pA of input bias current and ...

Said to be the industry’s smallest and lowest-power instrumentation amplifier, the AD8235 is well-suited for use in portable, lightweight medical devices and consumer health products. The in-amp ...
