.. 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 ...
.. problems and works well at speeds of 400 kHz or higher (Reference 2). References Nguyen, Minh-Tam, and Martin Baumbach, Two-wire interface has galvanic isolation, EDN, Nov 11, 1999, pg 174. Blozis, Steve, Opto-electrical isolation of the ...
.. 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, ...
.. bias voltage for Q 2 . The breadboarded circuit’s transformer, T 1 , comprises eight turns of AWG #30 insulated wire wound around the body of an unshielded 100-µH axial-lead inductor, producing approximately 400 mV p-p ...
.. 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 ...
.. the host. Figure 1. A typical LCD module. This hardware interface Design Idea (Figure 2) reduces the connection to just one wire, allowing a basic microcontroller with limited I/O to drive a large display, either directly, through a standard ...
.. (as in a relay or transformer) unless you can remove the iron. The resulting coil should be a simple solenoid like wire wrapped around a nail. Don't try to wind your own it takes too many turns. Evaluate several coils simply by ...
