The traditional analog function generator with its customary triple-threat ensemble of square, triangle, and sine waveform outputs is a familiar tool on electronics lab benches. It’s also a classical design exercise. Generally, the square and ...
.. but not wasting excess power when idle. The circuit of Figure 1 shows how an embedded processor can control its own supply voltage via a simple step-down converter and inexpensive digital potentiometer. Figure 1. Under control of ...
.. key part of any electronic device is the power supply. Any instability or malfunction of the power supply part causes the device to stop working or demonstrate ...
.. the simple VFC shown in Figure 1 is a variation on that basic theme. It’s adapted for operation from a single supply rail, with convenient and flexible differential bipolar inputs, and acceptable linearity while running at ...
.. voltage outputs of opposite polarity, are even more so. Figure 1’s version of a symmetrical 0 V to 10 V, 1.5 A lab supply implements an extra handy trick: computer programming via a single PWM output. Figure 1. LM337 , LM317 , and ...
.. condenser microphones require a 48-V supply to charge the internal capacitive transducer and power the internal buffer for the high-impedance transducer ...
.. contributor R. Jayapal recently shared an interesting Design Idea (DI) for power supply control and sequencing in MCU-based applications that combine analog and digital circuitry: “Short ...
