.. be programmed by the user. I used Altium Designer 21.4.1 and the SamacSys component libraries (SamacSys Altium Plugin) to design the Schematic and PCB. I also used the Siglent SDS2102X Plus/SDS1104X-E to analyze the IR signals. The device ...
.. analog-in, speaker-out power amplifier that I could pair with any source. In this article, I will walk you through the full design. Why TPA3221? There are dozens of Class-D amplifier ICs out there. The TPA3116, TPA3255, MAX98400 but the ...
.. temperature sensor with a standard digital multimeter can make an inexpensive, accurate, and useful thermometer. A recent Design Idea, BJT is accurate sensor for absolute temperature in Kelvin and Rankine ( Ref. 1 ), was based on a 1991 ...
.. ΔV BE temperature measurement is aptly described and applied here ( Ref. 1 ) by famed and forever remembered analog design guru Jim Williams (see page 7): At room temperature, the V BE junction diode shifts 59.16 mV per decade of ...
.. button cell, and automatically switches itself off when not in use, avoiding the need for an on/off switch. Introduction I design many of my projects for my own use, and the original Continuity Tester is one of the ones I use the most, to ...
.. (or otherwise)-caused cable cuts, and differentiating them from normal open circuits, is critical. Evolving the circuit design for expanded functionality makes it even more valuable. It’s just part of the job. Every design ...
.. the first part ( Ref. 1 ) of this Design Idea, we saw how a cheap op-amp can give remarkably precise readings from an RTD. We also found that it was a ...
.. the first part ( Reference 1 ) of this Design Idea (DI), we looked at simple ways of keeping critical components at a constant temperature using a linear ...
