When using the ADS component tuning feature you can tune values of components but usually the values you arrive to are not available and you need to go manually and tune them to standard values. Genesys has a feature where you can select the tuning values to be a percentage, a step size or...
Not really a very helpful answer but here's your answer. Anyone that has a lot of experience designing electronics will be faced sometimes with devices that have two or more versions. In this case the device has a version with and another without an output amplifier. In the one without we want...
I have a large design and there are sections of it that need to be disabled before netlisting it so that they are not sent to the PCB design software.
Are there any ways to "gray out" sections of the schematic so they're ignored and not netlisted? I just don't want to have to save a different...
Antonio,
If you don't have proficiency in soldering it will severely limit your ability to understand the consequences of solder in RF circuits which happens to be very important. Experimenting by seeing the changes that different soldering techniques do in the same circuit is quite revealing...
The actual reflow temperature is much higher than 100 degrees C.
SMD components should have no problem.
Here's an example of a reflow temperature profile:
If the keyboard lines are connected to lines that can be switched temporarily one to PWM and another one to ADC you could try generating a very high frequency pulse train sending it down the line and measure the disturbance it creates on the ADC line coming from electromagnetic coupling between...
Mystery solved.
Bought an evaluation kit for the part.
The evaluation kit's daughter-board worked with the PC software and the logic analyzer's SPI waveforms and timing were identical to the ones coming from the my Arduino so I unplugged the daughter-board from the motherboard and connected the...
I think you misunderstood what I wrote. I meant that as per the protocol it makes no difference that the clock pulses are 8+8 or 16 as long as the CS line is not raised the SPI takes the pulses both ways.
Yes I'm aware of that. If you see the code I posted above it says
SPI.transfer(0b00010000); // command 1= set pot, pot selected= 0
SPI.transfer(0b00000001); // pot value= 1
where the command C[3-0] is 0001 (write to the RDAC), the pot selected A[3-0] is 0000, then the data D[7-0] sent is...
If you look at the circuit there's a 2k resistor connected to the top of the pots and to 5V. The other side of the pots are connected to ground.
When the device powers up it loads 80h by default from factory so the wiper is in the middle of the travel and I get 5 * 5/(10+2) or about 2V at the...
Yes but the vias are there and the center square pad as well as the pins connected to the pad are grounded. If I turned the via visibility you wouldn't be able to read the pin names.
That being said lets not get off topic. I need help with figuring out why this particular IC is not responding...
Yes its grounded with vias to the ground plane layer in the square center pad. If you look at the layout its marked GND in pink. I just didnt activate the vias visibikity for the pic.
