  2. 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 ...

  3. 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 ...

  5. Jennifer Calhoon Design World A charge amplifier is not the most common type of amplifier, but very useful in the right circumstances, it is really a current integrator which produces a voltage output proportional to the integrated value of the ...

  6. Loren Siebert, Texas Instruments As high-speed systems become more complex and design cycles become shorter, engineers need to find high-performance yet flexible components to facilitate their system designs. One method is to use components that ...

  7. By Bonnie Baker EDN Europe Surprise, surprise. The bandwidth of an amplifier in a gain of +1 V/V is not the same as the bandwidth of the same amplifier in a gain of 1 V/V. After more than five years of working every day with amplifiers for an ...

  8. Roy McCammon EDN The traditional three op-amp differential amplifier's signal to noise ratio can be improved by 6 dB by adding a resistor and slightly changing the connections. There is a trade-off though: The traditional topology has a high input ...

  9. By Charly El-Khoury, Analog Devices This article shows how compensating an amplifier - such as the ADA4895-2 , which is normally stable for a gain higher than +9 -to operate with a gain as low as +2 provides higher slew rate and faster settling ...

  10. Vic Jordan, Carson City, NV It’s common practice to series-terminate an op amp to match the impedance of the load. This practice causes a 3-dB loss of output power in the termination resistance, however (Figure 1). Newer op amps operating on ...
