Slower transients can handled by rail capacitance. If you are running TTL level signals off board you need to worry about signal integrity as much as protection. If these signals are just between boards in a chassis, then what surges are you talking about? If they are between boxes, you pr...
In LTspice, I-V data can be measured using the.DCSPICE command/directive. The ground clamp of DOUT1 is measured using the setup in Figure 4. In the setup, appropriate supply voltages were applied to configure the device in a high impedance state (please refer to Table 5...

With power supply +/-Vcc and output voltage Vout, then the amp will burn a power Iout.(Vcc-Vout) as heat in the transistors and source resistors, and Iout.Vout is used as useful output power. So if you want higher efficiency, use a lower power supply voltage. Another way to increa...
The problem is that given those caps will then be both loading the output of one opamp, while also being used to stabilise it as a whole, mostly it seems this would produce oscillations from capacitive loading, from what I can see trying to set up the circuits in LTSpice. ...
than 500000 libraries with symbols and footprints of components and you will ever need, there is also a feature to create your own component symbol and footprint if needed. One more advantage is, it can support other software libraries and schematic which includes Altium, EAGLE, LTspice, and ...
(VCC, GND). These pins can be grouped and described together by the model. In this case, given that a SPICE model was given with no information about the internal transistor-level schematic, it is good practice to have a separate model for each digital interface. M...
I calculated the base voltage by Vb = R2/(R1+R2) Vcc [stiffed voltage divider] , but then when I'm asked to calculate the total power from the power supply when we remove the load, the base voltage changes. My question is why does the base voltage change af...
\$\begingroup\$ ,thank you.I understood the answer to my questions 1 and 3.For the second question, you said try the simulation.I simulated the circuit in LTSpice program. But I am getting results that have nothing to do with the results on the board. \$\end...
I know I need to add filters or even a new LDO, but I would like to find out where. All the sensors need stable VCC, I don't want to put separate LDO's/filters for all of them, just the one causing the noise. Logged dr.diesel Super Contributor Posts: 2214 Country: ...
