.. handy for air flow measurement. Maybe even moreso if it needed only a simple two-wire connection for both (phantom) power supply from, and signal delivery to, the supporting electronics. Please see the Related content listings below for a ...
.. by one step. Similarly, each “DEC” (decrement) push button press decreases resistance by one step. The power supply and ground pins of the various ICs are not shown in this schematic. This simple design uses only two ICs to ...
.. around an LM317 linear voltage regulator in a nice black plastic enclosure sold by Maplin Electronics as a “power supply” box. The NiCd battery hadn’t been used for over 20 years, so this project would be a repurpose. ...
.. fight each other and form an oscillator (Figure 3). The characteristics of this oscillation depend on pullup resistance, supply voltage, and capacitance data lines. (Removing one of the 9-pF scope probes stops the oscillation, and ...
.. many applications, you would like to hold the speed of a motor constant, even as variations in the power supply voltage or mechanical load try to change its speed. In other applications, the average current to the motor ...
.. particularly for designers who value analytical transparency and first-principles reasoning. It operates from a 5 V supply, commonly found in 5 V/1 A smartphone chargers, delivers 400 mA of constant current (CC), then transitions to ...
.. a 4-20 mA signal to 0-20 mA and deliver it to a grounded load with no additional power supply needed. Recently, EDN kindly published a design of mine for a micropower 4-20 to 0-20 mA current loop ...
.. tolerant, linear 4 to 20 mA, current mode output. Figure 3. Dangling the TLV431 shunt voltage reference Z1 from the 15 volt supply is a shortcut toward implementing a noise- and cable length- tolerant current mode output. Here’s how ...
.. can be set anywhere from 0 dB to 20 dB, for a total signal path gain of up to 80 dB. The project operates on a single +5 V supply, accepts input signals up to 1 V RMS, and produces output signal levels 1 VRMS (3 VP-P) into loads 5 kΩ. The ...
.. of the 4 to 20 mA input current to generate the 0 to 20 mA output while needing only microamps from its own local power supply. It consumes merely 250 µA × 24 V = 6 mW (typical) and dumps only similar single-digit milliwatts ...
