Part Number: THS3491 I saw a post regarding electro-migration stating that it isn't a concern for AC current, only DC current but I saw another post stating that for AC current one should check RMS current against the max. electro-migration limit of 100…
Part Number: THS3491 Hi, Support
In the datasheet of the amplifer, it only mentioned the gain resistor value selections on Rg and Rf.
Is there a requirement on the resistor package? how can we calculate the power requirement on these resistors??
also…
Part Number: THS3491 Hello Expert,
We are drawing schematic w/ this part for output ±25V, 300mA.
We'd like to email you privately for schematic review.
Could you please send to my e-mail (michael.jeong@arrow.com)?
We will share schematic.

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 So I was kind of working on Steve Smith's sim vs. measurement question and thought I would step through some things,
Here is the input current noise for the 2018 model - I had some analysis options set in V11 that was messing…
Hello Steve,
Wow, I cannot believe I did the classic "I will attach X" and forgot to do so. I believe Michael has reiterated it in his response, but I will append the TSC file here also:
7178.TINA Noise Sources revC (1).TSC
Best,

Hi Jordan,
I aggree with Alec. ESD could be the cause of damage. I heavily recommend to ship the assembled printed circuit boards in metallized ESD protection bags. Not the pink and transparent ones through which you can easily zapp ESD, but the metallized…
Hi Mita,
an OPAmp with a much higher supply current is a good candidate for lower distortion. A higher supply current allows the class AB output stage (and other internal stages) to be furtherly driven into the class A region.
But keep in mind that an…
