  • TPS7A30-49EVM-567: +/- Vin for initial operation

    Resolved
    Part Number: TPS7A30-49EVM-567 In the User's Guide (SLVU405–August 2010) for the board it is recommended, that +/-18V is used for the initial operation. In my application I have a fixed voltage source for Vin of +/-24V which is controlled manually, using…

  • TPS7A30-49EVM-567: TPS7A3001 output does not equal programmed output

    TI Thinks Resolved
    Part Number: TPS7A30-49EVM-567 Other Parts Discussed in Thread: TPS7A30 A TPS7A3001 is wired for a -5V output. R1 and R2 are selected to achieve a -5V output. However, Vout equals -3.9V instead of -5V. When SW1 is opened, the output changes to -12V…

  • RE: TPS7A3401: EVM and unencrypted model

    Hi Adam, I would use this EVM here it is for the TPS7A30, which has a very similar pinout. Typically for negative LDOs we recommend the use of TPS7A30 as you get the NR/SS pin included. https://www.ti.com/tool/TPS7A30-49EVM-567 I am working on getting…

  • RE: TPS7A49: voltage have fluctuation signal

    Hi Yu, I was actually able to get to this today. I reproduced the spikes you are seeing using the TPS7A30-49EVM-567. I used the default capacitors on the board. I tried removing all of the capacitors on the board, hoping that I could filter out the…

  • RE: ADS1675REF: self-programming for the use of ADS1675REF via the included XEM3010(Opal Kelly FPGA board)

    Resolved
    Hello, A good low noise lab supply with multiple outputs should work well. However, you can also use individual LDO's, which is how you would power the device when designing your own board. TPS7a3001 and TPS7a4901 are good options for the +9V and…
