In the ADS131M02 datasheet, there is a following schematic snapshot for interfacing the ADC differential input channel with the Current Transformer: Furthermore, Two identical burden resistor...
In section 6.5 of the data sheet is the snippet of the table you put in your question but, you possibly failed to read the default words at the top of the section: - $V_{S+} = 5 V, V_{S-} = 0 V$ ...
The mistake you made seems quite trivial. LTSpice recognizes your 20M as 20mHz (milihertz). If you want 20MHz, then you need to write "20MEG". That's all. However, when I ran your schm, I got a ba...
The below circuit is take from here. May I know how this circuit maintains the Potential at Reference Electrode and Working Electrode same. Here you can see that the working electrode is connec...
Trace width is a silly thing to worry about at such low currents and high impedances. You've got 1 MΩ resistances in the signal path, and the opamp input is presumably much higher impedance than t...
The sensed current may be at a +90V potential (VIN). The LTC2063 op-amp power supply range goes only to +5.25V . It's not a high voltage op-amp. So, the op-amp in this circuit floats just below ...
It might be something called a "pendulum detuner". The are designed to partially damp out the worst natural mechanical resonance frequency of the cable. Wind can excite resonance in a cable, whic...
I have built an ECG amplifier that uses an instrumentation amplifier and a driven right leg circuit to attenuate 50 Hz common mode voltage stemming from the body. A portion of the circuit is seen b...
Is there a scientific way to estimate the resistance of a pogo pin? Ultimately there must be, but it generally requires knowing things you don't know. Worrying about the resistance of the barrel ...
When should a transformer core be potted? Whenever you need some of Mechanical ruggedness. High dielectric strength. Minimize vibrations (and therefore audible whine) from capacitive, inductive...
My first knee-jerk reaction was to use opto-isolators. There are some that have been around for decades and are unlikely to go obsolete any time soon. I wasn't previously aware of these "digital ...
It depends on how you define "battery". I guess the definition is different depending on if you are a chemist, an engineer or a consumer. When electrical engineers speak of batteries, they typicall...
It has two female inputs on the backside that are labeled as "Grounding". This is incorrect. Take a closer look at the two connections and you will see that the left is labeled "Antenne" and t...
I am determining the Area-Product of the core required for a transformer to be used within a series resonant converter. The specifications are as follows: Switching frequency = 400 kHz Primary ...
The website that I mentioned before mentions the max flux density in ferrites at 400 kHz as being close to 0.04 T. Is this correct? No, you have misinterpreted the graph. The graph shown is fl...
A loss-less coaxial cable has inductance and capacitance and, their associated formulas introduce $\epsilon$ and $\mu$. But, to home-in on the velocity of propagation, the characteristic impedance ...
I want to know why the top-of-the-line CPUs and GPUs from Intel, NVIDIA, and AMD are all bragging about the fabrication process (7nm and 5nm) and trying to be consistently smaller. At the same tim...
Started writing a comprehensive answer, interrupted by some phone calls, finally finished it...and then accidentally clicked to another page and lost it. Arghh!!! So this answer may not be quite as...
Preface English isn't my first language. I'm still pretty green relatively as an electrical engineer with 3 years out of B.S. program and in the medical industry. This is my first post on any st...
Do common-source JFET amplifiers have an advantage over common-drain? The JFET would be in a low noise photodiode amplifier. The signal is 100us pulses with 10us raise times. Here are the schema...
I've done a lot of work on tags lately and I'd like to share with the community some thoughts about the way tags should be named so that maybe it could become part of the FAQ and so hopefully lead ...
I just submitted a proposal to DuckDuckGo here for a new "bang" for their search syntax. If approved: !coddee search_term will trigger the following URL: https://electrical.codidact.com/posts/se...
Yes, votes on meta should not factor into rep. Meta downvotes indicate disagreement, not that you're a terrible person, have the IQ of a garden slug, and cast dispersions on your heritage like the...
Yet another example. If using MOSFETs only for power switching applications, it can seem like these are "robust" and "immune" to ESD events. While the package clearly states "ESD sensitive", devi...
