Hi Alberto Sanchez Garcia,
THS4561 is supported by another team at TI, you can post your query in the Amplifier forum to get the best support.

i was a bit rushed to get out the door yesterday, I had missed changing the lower feedback cap, more time this AM.
the original RC backs out to gain of 1 2kHz Butterworth (Q=0.71), keeping that target and running a lower integrated noise with best fit…

Hi Vishal,
Thank you for your question! As Michael mentioned, the THS4561 would be a good alternative device. The THS4561 has a faster slew rate, lower current consumption and improved DC precision for similar bandwidths & supply as the LT1994. We have…
Also, if you need better DC precision consider the THP210 for higher voltage or the THS4561 midrange supplies, THS4551 5V only. All superior DC error terms, but a bit higher noise. Part of the tool Sima mentions will calculate noise, a lot of that will…
Thank you, Keith. The circuit showed great results. I noticed the -300mV on the negative rail.
There is a -5V negative rail in the design. In this case, would it be a better solution using THS4561 (BW, Offset not as good), or OPA862 and THP210?, Using…
Part Number: THS4551 Other Parts Discussed in Thread: INA213 , INA851 , THS4561 Hi, In my design I am using THS4551 part, may I know what the maximum differential input voltage range ? And what resistor value use(Rs shunt resistor between differential input…
