Xiyao Zhang, Texas Instruments Early in my graduate school education, I was working on a project that needed a unity-gain operational-amplifier (op-amp) buffer for a monitoring circuit in our thin film deposition system. As soon as the new module ...

Brandt Braswell EE Times I know there have been many advances in software development for use in design projects. The digital design landscape has permanently been altered by the use of sophisticated software tools for use in design. Design tasks ...

A simple op amp clipping circuit can limit input-voltage excursions into an ADC, thus preventing input overload and possible damage to the converter. It can be a challenge to match the voltage range of an analog signal to the input range of an ...

By Gustavo Castro and Scott Hunt, Analog Devices Analog Dialogue Instrumentation amplifiers (in-amps) can condition the electrical signals generated by sensors, allowing them to be digitized, stored, or used to control processes. The signal is ...

Darwin Tolentino and Sandro Herrera, Analog Devices Analog Dialogue Differential signaling finds useful application in circuits where a large signal-to-noise ratio, high immunity to noise, and lower second harmonic distortion are desired, such as ...

Gustavo Castro, Analog Devices Analog Dialogue Question: Why is the effect of common-mode signals at the output larger than the CMRR specification? Answer: The concept of common-mode rejection ratio (CMRR) is fundamental when working with ...

Chris Francis Design World There are many reasons for needing to filter power supply or signal lines. Power supply lines from a switching regulator may be too noisy for sensitive analog circuitry. Signal or power supply lines may pick up ...

By Moshe Gerstenhaber, Rayal Johnson, and Scott Hunt, Analog Devices Analog Dialogue Introduction Building a voltage measurement system with nanovolt sensitivity presents many design challenges. The best available op amps, such as the ultralow ...

Glen Brisebois, Linear Technology Design Note 533 Introduction Linear Technology’s Over-The-Top® op amps have an input stage topology that allows them to operate closed loop well above the positive supply rail. The inputs remain high ...

David Hunter, Analog Devices Analog Dialogue Part 1. The AD8338 Input Network For this design, the differential output amplitude will be 1.0 V. With factory default settings, the internal 500 Ω resistors, and maximum gain, the input amplitude ...
