Part Number: VCA2615 Hello! We have some questions when using vca2615rgzt. I hope you can give me some help and answers. Problem: we use vca2615 as part of automatic gain control. Under the condition of almost the same input and output, the maximum difference…
Carlos,
I looked at the model and its noise simulation plot . The model is designed to have about 5.5n v/ZH^1/2 for VCA and 0.7n for LNA. Please keep in mind these are measured from 1M to 10MHz as are depicted in fig 24 and 25 of data sheet. For frequencies…
Part Number: VCA2612 Other Parts Discussed in Thread: VCA2615 Hi,
I am just checking if the VCA2615 can also process DC signals.
If I look at the datasheet block diagram on page 2 I see internal coupling capacitors, making the device not usable…
Part Number: VCA2615EVM Other Parts Discussed in Thread: VCA2615 , We Ordered VCA2615EVM evaluation board (1590276) almost one month ago but when we tested it, it did not give good result to us, after a few days we tested and worked with that board, one…
Other Parts Discussed in Thread: VCA2615 Hi,
I would like to ask you a question about VCA2615 ESD specification.
Could you tell me the specs of ESD(HBM and CDM)?
Because there is no description about them.
Thank you for your support.
Best Regards…
Hi,
I have one question about the Vclamp function.
I think that the description of "Fig 48" and the explanation of datasheet "page 22" seem to be different.
<Fig 48>
<Page 22>
Though page 22 explains that "Vclmp is equal to the peak differential…
Other Parts Discussed in Thread: VCA2615 , VCA2617 , AFE5809 , AFE5801 Hi,
We are designing a sonar system where the signal is at 100kHz. since the space is limited and critical in our system, we want to use integrated ICs, rather than op-amps or instrument…
Avishai,
The VCA2615 is handled by TI's Medical/ Hi-Rel group. They have an E2E forum and should be able to answer your specific VCA2615 questions.
I am not very familiar with the VCA2615, but when I look over the section it speaks about the low-noise…
Hallo,
on page 18 in the data sheet are two formulas. Number 5 which uses A/2 and number 6 which uses A.
I guess formula 5 is for differential signals and formula 6 for single ended.
Is that right?

Amy,
Yes, I want to tie the Vocm of THS4131 to the Vcm of VCA2615.
But judging from the functional block diagram, the Vcm pin of the VCA2615 comes from the VCA part and not the Low Noise Preamplifier(LNP). But I want to use both the LNP and VCA features…
