.. circuit in Figure 1 can help if you must transfer dc power and audio over a pair of copper wires. One application for such a circuit is a low-cost door-opening system ...
.. ADC itself, often with a maximum offset spec that is well above that of the ADC. If multiple ADC channels are required, the power dissipation from these drivers quickly rises to unacceptable levels. If 18-bit precision is required (SNR, THD, ...
.. only a cursory look at the input-voltage ratings of your power-supply IC can limit the usable input-voltage range. With careful examination of an IC's operating ...
.. electronic devices may suffer in twilight conditions. In particular, microprocessors often used to perform solar power conditioning (such as in maximum-power-point trackers) do not like unstable power or smooth edges on power-up. ...
.. circuits normally monitor a microprocessor's supply voltage, asserting reset to the IC during power-up, power-down, and brownout. In this way, the circuit ensures that the supply voltage is stable before the ...
.. Martin Lithium-polymer (LiPo) batteries have a higher power density than most other battery technologies. They also deliver a higher nominal voltage per cell: 3.7 V ...
.. diodes often have a dropout voltage of approximately 1.2V for silicon power diodes. That voltage drop causes power diodes to dissipate considerable power, resulting in a loss of ...
.. a recent design project, a robust power supply was needed to control the gates of high-side FETs. Optocouplers readily translate the logic signals up ...
.. into whatever load is reflected. It would be useful if you could predict/measure the impedance seen to optimise the power amplifier design, but an L or Pi network and standard antenna matching techniques can be used. vk2zay.net
