.. 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, ...

.. part of the circuit comprises two conventional noninverting stages. The proposed circuit can be useful in many two-wire or two-electrode applications, in which you need to maintain high amplifier input-impedance values. Figure 2. ...
.. At the same time, the minimum-allowed transmitter-terminal voltage, which determines the maximum loop length for a given wire gauge (or the minimum wire cross-section needed for a given loop run), should be minimized. The transmitter ...
