Hello Samir and Livingstone,
In addition to Samir's comments, here are my inputs to your questions:
1) Photodiode / Mimicking a current generator: If you can use an actual photodiode for bench testing, I found some which are close to the 70pF terminal…
Hello Julien,
You could use TINA-TI to simulate the amplifier along with the expected loading from the ADS1251 and the parasitics from your PCB to see if you have a potantial stability issue.
With regards to testing functionality, I think when using…

Other Parts Discussed in Thread: TPS2411 Greetings we are using the TPS2411 for a redundant power supply design and during the test process we encounter some unusual behavior from the oring controllers. A shcematic of the circuit is below:

HI John
Thanks for the feedback
I’m waiting to receive some OPA657 to test then on a DEM-OPA-SO-1A .
The 6kOhm feedback resistor on the TIA was the value that was working “on the bench” according to the simulated. Higher gains on the TIA were not…
Hi Feixiao,
I bread-boarded the OPA657 as a transimpedance amplifier (gain = 22kV/A) and tested it with a bench generator and I got good results + no instability.
Here is the TINA-TI circuit which simulates closely with the measured results:
5432.OPA657…
Hi Michael,
Thanks for catching this. We will try to get this fixed but in the mean time here is the BOM for the TIDA-00874. BOM-TPA3251D2REF1.xls

Hi,
It may not need to run in FDU mode. You can add MSPM0_BSL_GUI.exe in SDK installation folder\tools\bsl\BSL_GUI_EXE. Modify the attach file name from .txt to .exe
MSPM0_BSL_GUI.txt
Then run the .exe file. In MoreOption->Update XDS110 firmware. …
