Hi Kai,
Thanks for your reply! Thomas (who answered my previous forum) suggested me to ask the people in the E2E forum of High Speed Amplifiers product group for the 3rd question and I personally also want to hear their advice about whether THS3122…
Other Parts Discussed in Thread: THS3122 Hi All,
I am designing a high power circuit for a transducer application. I see in the data sheet of THS3122 that output voltage swing is around 13v for +/-15 supplies. does this mean that output can swing…
Hi jQ,
Please see my responses to your questions:
1. My first question is that whether OPA564 is also a choice? My main concern is its GBW, which is 17 MHz. Suppose the gain is 20, the BW is then 17M/20=850 kHz, does that mean it is still sufficient…
Other Parts Discussed in Thread: THS3122 , TINA-TI I want to simulate a unite feeback circuit,but I found the following problem: The Input：2Vpp，10MHz sine wave： My circuit：
When the feedback resistance is 100k(As above),the output is just 120mVpp…
Hi Yatao,
to get the full heat dissipation of THS3122 the current through R3 and R4 would even have to be added, actually, as the current running through them also have to be delivered by the OPAmp and also create a heat power within the THS3122 :-…
Part Number: THS3062 Other Parts Discussed in Thread: THS3122 , OPA2691 , OPA2694 , OPA2684 Are there some alternative TI parts that could be a drop in replacement for a THS3062D? This is the SOIC 8 pin, no heat slug on the bottom.
Can be same slew…
Hi Sima,
I will try to explain where is the catch with the OpAmp and why we want to do first the simulation with LM6172.
We chose CSD19534Q5A transistor, and we need to choose the OpAmp that drive the gate of the CSD19534Q5A fast, meaning when we…
Hi Ronald,
I think THS3062 (current feedback amplifier, 300MHz unity gain bandwidth, 7,000 V/us, +/-15V capable, dual), or THS3122 are good possible candidates to try in place of the LM6172 (although I'm only going by the datasheet specs and I've not…
