Intellectual 500 points
Part Number: ADS5296A
Other Parts Discussed in Thread: THS4541, , ADS5296, ADS52J90, THS4509

Hi,

I want to drive the ADS5296A with differential op amp. (THS4541)

pls. provide reference schematic.

in addition could I drive the ADS5296A with single ended signal?

if yes, pls. provide reference schematic.

    Hi Zeev,

    Let me find out the schematic or any reference design with ADS5296 and get back to you by tomorrow.

    Thanks

    Hi Zeev,

    I am consulting my team to provide you any available design document of driving ADS5296A with a differential opamp THS4541. 

    Out EVM schematic also doesn't feature any amplifier to drive the ADC.

    Hence, so far I haven't found any existing document. 

    Please allow me some more time to figure out a way to support this. Will let you know by Monday.  

    Thanks & regards,

    Abhishek

    Hi Zeev,

    I checked for the collaterals of AFE5296A to be driven with amplifier THS4541. Unfortunately we do not have any reference schematic with THS4541. However, I have a reference schematic for the ADC ADS52J90 with THS4509.

    Regarding your question, in addition could I drive the ADS5296A with single ended signal?

    No, you cannot drive the device ADS5296A with Single ended input primarily because the common mode voltage range of the device is 0.95V +/- 0.05V which will not provide the complete swing of the input in single ended mode.

    I hope this answers your question. 

    Let me know if you have further questions.

    Thanks & regards,
    Abhishek
