.. common in industry. This circuit implements current loop conversions for them. Recently, there have been several published Design Ideas on converting 0/20 mA to 4/20 mA current and 4/20 mA to 0/20 mA current as full-circle current loop ...
.. always gratifying when a simple and successful design idea luckily turns out to have additional applications that you didn’t originally envision. ...
.. current flow, ensuring a smooth and efficient start-up, while protecting your equipment from damage. So I decided to design this AC soft starter that is equipped with a fail-safe mechanism. During start-up, the inrush current passes ...
.. small signal BJTs can function in simple circuits as 0.1% precision absolute temperature sensors, as shown in an earlier Design Idea ( Ref. 1 ). The ΔVbe effect depends solely on the ratio of applied currents, independent of their ...
.. to a standard circuit can enhance its usefulness and even save a resistor. If there were a prize for the most trivial Design Idea (DI) of the year, this one would likely be high on the shortlist (if not at the top). Most DIs involve ...
.. goes LOW, turning Q1 and Q2 OFF. The 5 V output, switched OFF last, implements the desired FILO sequence. Notably, this design doesn’t employ a constantly power-consuming watchdog circuit. For different time delays, accordingly ...
.. 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 ...
