Part Number: ADS61B49
Dear technical Support Team,
As the Christmas season approaches, TI will gradually begin their holiday break, so I would like to resolve this as quickly as possible.
Despite inputting 100MHz, it was no longer operating in LowSpeed…
Part Number: ADS61B49 The previously designed board incorporates the ADS61B49IRGZT. A failure was confirmed in this component, and we replaced it.
After replacement, phase alignment errors began occurring. Debugging revealed that switching the ENABLE…
Part Number: ADS61B49 Tool/software: Dear TI,
I have a question about ADCs and the potential metastability issue. Specifically, I'm concerned about the internal comparators in the ADS61B49 architecture.
Could metastability in these comparators trigger…
Part Number: ADS61B49 Dear Technical Support Team,
ADS61B49 datasheet has figures "SNR /SFDR vs Ta". (Figure 25～28)
Do you have figures of them based on thermal resistance and junction temperature ?
Do you have thermal resistance(ψ) data?
Best…
Q1) I'm looking forward your reply.
>Q2) Connect SEN to digital ground. This is enable for the SPI interface
⇒ The datasheet of ADS61B49 said that SEN has internal pullup to AVDD(analog power).
Is it ok to connect pullup(AVDD) to DRGND(digital ground…
Part Number: ADS61B49 Other Parts Discussed in Thread: ADS6125 I am just trying to design a waveform capture board based on ADS61B49 high speed ADC.
On the ADS61B49 product page, there are links to ADS6125 evaluation module and TSW1405 capture cards…
Part Number: ADS61B49 Hi,
My ADS61B49 sometimes make output code of 0x3FFE (11111111111110) even if the input differential voltage is around 3V. Sometimes the same chip output code goes 0x3FFF.
I got such devices on my 2-3 boards (chips) out of 8…
Other Parts Discussed in Thread: ADS61B49 Hi,
Please help me in length matching ADS61B49 DClock output and Data lines in the PCB design. What is the acceptable length difference between the Clock and Data at sampling speed to around 160Msps.
Thanks…
Hi,
yes, the toggle pattern is alternating 0xAAA and 0x555. That is, 1010 1010 1010 and 0101 0101 0101. That way every bit is toggling on every sample, but also the bits within each sample are not just all 1 or all 0. Sometimes this is also called a…
Other Parts Discussed in Thread: ADS4129 , ADS61B49 , ADS5403 , ADS6129 , ADS5474 Hello
TI is the manufacturer of such ADCs as ADS6129, ADS61B49, ADS4129, ADS5403. The data sheets on these devices don't specify the appearance of error codes due to metastability…
