By doctorj, on July 9th, 2009% This concludes the series of tutorial videos on the R2R ladder network circuit as an example of operational amplifier design and applications. The video will continue to discuss the 4bit digitaltoanalog converter (DAC) and R2R ladder circuit using the superposition principle to analyze the DAC. After viewing the above video on the R2R digitaltoanalog converter [...] . . . → Read More: OpAmp Design & Application Tutorial – DigitaltoAnalog Converter (DAC) Circuit R2R Ladder – Part 5
By doctorj, on June 30th, 2009% We use the same example from the previous article. The video will show once again how to go from an inputoutput relation described as an algebraic equation to a block diagram form. In this design, we use fewer number of op amps to implement a circuit describng the equation. To summarize, the previous two articles [...] . . . → Read More: Op Amp (Operational Amplifier) Design and Circuit Tutorial (Part 3)
By doctorj, on June 28th, 2009% A series of videos showing how to do interface design using operational amplifiers. The videos shows how to maximize the power delivered to a load using a noninverting design and an inverting design. Loading effects of the inverting design are briefly discussed. Some of the links in the post above are “affiliate links.” This means [...] . . . → Read More: Op Amp (Operational Amplifier) Design and Circuit Tutorial – Interface Design – Part 1
By doctorj, on June 15th, 2009% The following configuration for the operational amplifier is known as a difference amplifier or subtractor. You can think of it as a combination of an inverting amplifier and noninverting amplifier discussed earlier. You can use the concept of superposition to get the desired results. Some of the links in the post above are “affiliate links.” [...] . . . → Read More: Operational Amplifier (Op Amp) Tutorial – Difference Amplifier or Subtractor Circuit
By doctorj, on June 13th, 2009% The previous videos talked about the inverting amplifier as a single input device and as a summer. When implementing the inverting amplifier, loading effects must be considered. In other words, when hooking up circuits together the circuit or mathematical operation may change for each circuit after being connected with one another. Some of the links [...] . . . → Read More: Op Amp (Operational Amplifier) Design Basics – Inverting Amplifier – Loading Effects –
