Hello Forum,
While a discussion around the specifics of this support request has been occuring over email, the relevant information for the forum is correct power down implementation. Please refer to the datasheet when designing power down features into…
Part Number: THS3491 Other Parts Discussed in Thread: TINA-TI Simulations for THS3491 generally seem to work but when adding a 100 pF load capacitor with a 1 ohm series resistor the output oscillates. The model has caveats about simulating other than standard…
Part Number: THS3491 Hi
We use the THS3491 in our production and have seen one instance out of several hundred where a THS3491 is fitted to a PCB, tested and working perfectly, then we package and ship the device somewhere else.
Our product uses 20 THS3491s…
Part Number: THS3491 Other Parts Discussed in Thread: OPA2677 Hi Team,
Please advise on the following question.
I consider to use THS3491 in a system which requires stringent HD2 and HD3 performance.
The THS3491 datasheet insists HD2 and HD3: Less Than…
Part Number: THS3491 I'm looking for some guidance on how to interpret the TJ_SENSE specification for the THS3491. Since the test condition is to disable the part (Pd = 0V), the Ta is somewhat close to Tj, but what does the temperature value on parameter…
Part Number: THS3491 Other Parts Discussed in Thread: OPA2677 , Hi,
The Typ values for HD2 and HD3 are listed on page 6 of the data sheet.
Could you tell me the Min/Max value of this value?
Or could you tell me the sigma value of the normal distribution…

Hi Experts.
Thank you for your support.
and I'm getting very valuable informations on this site and your advices.
This question is same project of my last thread.
but unlike that thread,
I also have to make voltage source (buffer…
Part Number: THS3491 Hello, I would like you to confirm whether THS3491 can accept unity gain setting or not. Because, according to datasheet, it seems that all spec is defined as 5V/V condition. Could you please tell me concern about unity gain setting…
Hi Winwoo,
the THS3491 is a current feedback OPAmp and current feedback OPAmps don't like such low pass filtering caps in the feedback loops. Run a the
THS3491DDA TINA-TI Reference Design (Rev. A)
and look what happens when you add a Cf.
