TLC5540 — DC level at ADC input creating errors

All content and materials on this site are provided “as is”. Jan 21, 2: In reply to Jim Brinkhurst Even the signal source as well as the input signal applied to the device is same as earlier. Jan 1, 3: Best regards, Jim B. Please see snapshots below. I think you need to simulate your input circuit to see the response that it is providing.

Jan 2, 4: Input to analog switch in AC path 3. You said “It tlc55440 best to use a single 9-bit or larger translator for the 8 bits and the clock to minimize skew between data bits and clock. The speed is slow enough that there is quite a bit of timing margin, so it may not be too critical.

Ask a related question What is a related question? Output of analog switch in AC path 4. In reply to lei gong:.

For your 5V reference, the signal should be centered at 2. Content on this site may contain or be subject to specific guidelines or limitations on use. Therefore you need to bias the ADC at 1. What is the voltage at pin 5 of U12? Jan 17, 1: If the clock driver is far away from the TLCyou may need to properly terminate the transmission line to avoid overshoot and avoid tlc5540 the absolute maximum voltage levels.

When the clock is not driven from FPGA, the offset drops down to zero. No license, either express or implied, by estoppel or otherwise, is granted by TI.

Do you alternate which is open and which is closed? Regarding your divider, can you tell me your expected analog input voltage range?

This thread has been locked. So we isolated the comparator input from the circuit by removing the series resistor R We tried to change back to the previous configuration too.

But when the clock signal is applied, even when no other circuit is connected to it, the ADC shows 1. If you can provide a description of exactly what you expect the circuit to do, I may be able to help. The ADC does not set the DC bias at the input, take a look at figure 13 in the datasheet to see that it is high impedance. Trademarks Privacy Policy Terms of Use.

We have limited ourselves to work with 1Vpp signal now such that the input voltage doesn’t go higher than the ADC’s input range with the DC offset. The newly created question will be automatically linked to this question. Do you have another question? In reply to Matt Guibord:
