Part Number: ADS5546 Other Parts Discussed in Thread: ADS5560 , Tool/software: Hi Experts,
I understand that the Theta JC specification mentioned in the datasheet is referring to the bottom. May I have the Theta JC top specification?
Keep safe.…
Part Number: ADS5546 Hello,
The datasheet didn't describe the relationship about the input voltage VS output code. For example, if the input voltage is 0.75V , what is the output code?
Below is the configuration:

Hi,
There was a screenshot in the test document that did not come through in copying and pasting into the posting. I am attaching the document itself. Also, back then we had a batch file that we would run that would handle the Xilinx JTAG programming…
ALB,
Is your EVM a Rev C board? If so I have attached the schematic. Please make sure all jumpers are set per the board photo I am sending. Take a scope probe (diff probe would be better) and monitor the ADC input across R21 and R26. You should see…
Jin,
The schematic looks good for the most part. Please do the following:
1. Install R364 to provide a path to GND.
2. Do not use R361, R362, and R363 wit the ADC_VCM output.
3. Make sure DRVDD and AVDD are 3.3V.
4. Do not need to route ADC_CLKOUTM_F…
Hello Jim,
Apologies for the late reply. I have been traveling and have now just starting to catch up to all the E2E questions.
The revision C of the schematic is attached. The major change on this revision is that we have replaced U15 from a 16-bit…
Couple of quick things Akash,
1. Where is your DC bias current path for the V+ inputs to the op amps?
2. This differential I/O op amp circuit sometimes has a common mode oscillation - probably not here, but we did see that in the OPA838 decomp device…
