  • Designing at Very High Voltages:

    Translate this pageFigure 2: To minimize IR losses in cables, connectors, magnetics, and active components, motors are designed to operate from mains at very-high voltages. The way to minimize these losses is to increase the voltage and thus reduce the current, thereby reducing IR losses and I 2 R heating.

    Whilst high bit-count is important, it’s not the only factor that is important. When dealing with small voltages, your ADC needs to be low-drift, have a very stable reference voltage, and have sufficient bandwidth to capture your signal. A high bit-count on an unstable or drifting ADC will still give you inaccurate readings.
