.. For this circuit, these conditions correspond to a full-scale output of 39 mA and a resolution of 150 µA. The three-wire serial interface that controls IC 1 allows you to shut down IC 1 by writing code 00hex to the DAC. The circuit ...
.. pot (0) to the other end (1). R is the end-to-end resistance of the potentiometer. The XDCP's programming uses a three-wire bus. The potentiometer is configured as a two-terminal variable resistor. The regulator's ERROR output signal ...
.. serves as the clock input to the stepper-motor controller. Writing to the frequency-control registers via a simple, three-wire interface sets the clock frequency. Writing a 0 to the frequency register stops the clock, thereby stopping the ...
.. loops offer robust noise immunity and tolerate long cable runs. These advantages, combined with simple unshielded two-wire cabling, make this mature signaling standard popular for transmitting analog data in noisy industrial and process ...
.. of the main pass transistor. In this setup, however, Q 2 dissipates only around 50 mW, so it can use just a jumper wire for R 5 hence, the schematic shows it with a value of 0 Ω. Two identical circuits on a round PCB ...
.. of the data and sync pulses is 3 to 12 V p-p, with one cycle of an ac wave representing each bit. The signals are on a two-wire cable that you can isolate from ground by using signal transformers or capacitors. Several other ...
.. outputs can deliver logic levels of 2.5 to 5 V. The programming interfaces for both devices comprise two three-wire (plus ground) SPI connections that use only six of the controller’s signal lines. Figure 1. A programmable ...

.. either or both of two common interface standards SPI (serial-peripheral interface) and I 2 C (inter-IC)/SMBus. Both two-wire-interface standards suffer from a few crucial disadvantages. For example, I 2 C's throughput rates are 100 ...
.. with R = 390 W is clean with well-defined transitions. Post-transition aberrations are within 8% and derive from G 1 bond-wire inductance and an imperfect coaxial probe path. Figure 3 shows a 5 V, 5 ns width, measured at 50% amplitude, ...
