Bill Schweber, Analog Devices EDN A lot of the analog-circuit conversation these days is centered on low-power and thus low-voltage considerations. That makes sense for operational amplifiers (op amps), of course, since these basic analog building ...

Part 1 Preserved DC Precision In a typical operational amplifier circuit, a portion of the output is fed back to the inverting input (Figure 9). Errors that are present on the output which were generated in the loop are multiplied by the feedback ...

by Jino Loquinario, Analog Devices Analog Dialogue Introduction It is normal, and almost expected, to be faced with applications for which a solution does not appear to exist. To meet their requirements would require us to think of a solution that ...

Rien Oortgiesen, Jens Tybo Jensen, Infineon Technologies Part 1 3.2 Benefits of multilevel class D The benefits of innovative multilevel class D amplifiers include: Smaller solution size and lower cost with less reliance on filters Improved ...

Rien Oortgiesen, Jens Tybo Jensen, Infineon Technologies Traditional class D amplifiers present significant design challenges in compact applications such as portable consumer sound systems and smart speakers. These challenges include relatively ...

Rusty Juszkiewicz, Analog Devices Analog Dialogue Question: Can we generate a differential output signal using instrumentation amplifiers? Answer: As the drive for precision moves forward, fully differential signal chain components are desired for ...

Greg Davis Electronic Design Whether it’s a vision-correction medical instrument or factory press, INAs offer an excellent way to amplify microvolt-level sensor signals while simultaneously rejecting high common-mode signals. In the past, the ...

Thomas Tzscheetzsch, Analog Devices Analog Dialogue Question: Could I use the disable pin of an amplifier to save power without losing performance? Answer: Battery-operated applications are becoming popular in the IoT era. In this article, we will ...

Paul Blanchard and Brian Pelletier, Analog Devices Analog Dialogue When external overvoltage conditions are applied to an amplifier, ESD diodes are the last line of defense between your amplifier and electrical over stress. With proper ...

Daniel Burton, Analog Devices Analog Dialogue Question: I’m selecting an op amp for my precision signal path. Isn’t faster always better? Answer: Choosing the appropriate bandwidth for an application of a precision op amp is a lot like ...
