Hirotaka-san, Sorry for the delay. As far as your questions goes. In order to modifiy the EVm to allow DC coupling you will have to remove all of the transformers (T1) and install 0 ohm resistors in their place. (use 0-ohm to bridge 1-6 & 3-4). If your…
Hi Chen,
I've downloaded EVM user guide. Thank you.
In EVM schematic there are only two options: transformer or very wide BW diff. amplifier. I have single ended signals with limited BW (about 100MHz) i.e. I don't need power hungry fully differential…
Part Number: ADS4128 Other Parts Discussed in Thread: THS4541 , THS4509 , TSW2170EVM , TSW2110EVM Hello,
I have an application with an ADS4128 driven by an AFE using THS4541 and THS4509 op amps.
I want to be able to reproduce the setup used in figure…
Hi Sina,
For driving the ADS42LB69, I would recommend using either the THS4509 or the LMH6554 in-order to achieve an SNR > 70-dB.
I would recommend looking at the following design guide using either THS4509 or LMH6554 for your application. The design…
Hi Seungik,
For questions about THS4509 please create a new forum post with THS4509 in title so that someone from amplifier team can answer your amplifier question.

Hi,
If you need to sample a bandwidth that goes all the way down to DC, then you can't AC couple, obviously. Yet, there still needs to be some kind of signal conditioning to the input signal to put it into the format that the ADC analog input requires…
Hi SM,
I realized an error I had made in terms of the THS4509 headroom calculation (I had meant to consider the Min / Max datasheet columns but incorrectly used the Typ number).
I've corrected my errors in color above.

Hooman
