Other Parts Discussed in Thread: ADS61B29 Hi,
I'm using ADS61B29 ADC. I'm feeding 4dBm input so that i'll get -6dBFS. The time domain plot is as follows :
Initially the amplitude is Full scale and then it came down to -6dBFS. Over range of ADC is…
Other Parts Discussed in Thread: ADS61B29 Hi,
I'm looking for a MATLAB code which will do the FFT calculation similar to wavevision. I want this for plotting the captured data of 12 bit ADC ADS61B29 .
FFT Window : Blackman Harris
Bins to omit…
Other Parts Discussed in Thread: ADS61B29 Hello,
I want to ask a question about the Power Supply Rejection Ratio(PSRR) of ADCs/DACs. For example in the datasheet of ADS61B29 PSRR is given as 25dB. If sampling frequency is 250Msps then the end point…
Hi Steve,
We have some 12b ADCs that have a buffered input. Would this meet your needs or do you need an external amplifier? Please check out the ADS41B29 and ADS61B29 at 12b 250Msps.
We also have a 16b 250 Msps with buffered inputs - It is a dual…

Dear Technical Support Team,
I have three questions about ADS61B49. See attached file.

Q1)
Could you show the region of AVDD/AGND and DRVDD/DGND for…
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…
