.. turned on. Performance is far better than a FET, and unlike analogue switch ICs, you don't need to mess around with odd power supply voltages. In the off state, distortion is typically less than 0.004% and attenuation in the on state is ...
.. The cycle repeats at a frequency related to time constants within the bias network. Poor circuit layout or inadequate power-supply decoupling can also cause squegging. These causes are readily addressed, but the solution to the ...
.. rating isn’t much of an issue. A cool feature of this simple topology is that, unlike many other schemes for digital power supply control, only the regulator’s internal voltage reference matters to regulation accuracy. Precision ...
.. time proven Bob Pease masterpiece! However, unlike the earlier design idea that requires a floating, fixed output 24-VDC power adapter, this sequel incorporates a ground-referred boost preregulator that can run from a 5-V regulated or ...
.. a constant current of 400 µA through the grounded sensor, T 1 . Driving T 1 with this level of current “zero-power” operation keeps the worst-case power that the circuit dissipates in the sensor to less than 40 µW ...
.. design idea (DI) takes an unusual path to a power-handling DAC by merging an upside-down LM337 regulator with a simple (just one generic chip) PWM circuit to ...
.. dependent, ranging from 500 Ω at 5 V to 200 Ω at 15 V. If the current demand of the connected load is low enough, then power can be taken directly from F1b pin 13 and the Q1 MOSFET is unnecessary. Otherwise, it is, and a suitably ...
.. protection is an obvious requirement for a power supply, especially when its load connects to a cable that's subject to damage. Many modern power-converter ...
.. The transistors are preferably Darlington types and, like the diodes, should have adequate ratings to accommodate the power-supply voltage and the motor current. (Don't forget the high inductance of the motor.) The components in ...
