Part Number: ONET2591TA Other Parts Discussed in Thread: OPA657 , OPA843 , OPA846 , OPA847 I found an application note, sboa122.pdf that discusses how to calculate the maximum achievable bandwidth for TIAs. It uses the OPA847, OPA846, OPA843 and OPA657…
Part Number: DAC3174 Dears,
Could you help to review the two schematic, thanks!
two DAC are synchronized;
Output ±5V single-ended signal;
100MSPS

Hi Shreeneet,
There are many solutions to attenuate a signal, please refer to the following app notes and previous queries on TI amplifier forum:
Attenuator Amplifier Design to Maximize the Input Voltage of Differential ADCs
Designing Inverting…
Thank you for your advice Mike. I have decided not to use the OPT101 because its bandwidth is only 14KHz. My signal is at 445KHz. Instead, I was planning on making my own transcendence amplifier with an OPA843. Though the 1.5GHz bandwidth is a bit excessive…
Thank you for the reply friend
My first requirement is band width 1khz to 5Mhz (I know this op amp is too much band width but I tried several op amp but this one is the only one work for me-THS4215,THS4203,OPA695, OPA847ID OPA846,OPA847,OPA843)
I…
Well Mark, I think you meant to say low phase margin as an attenuator, not phase reversal - if the op amp is unity gain stable, that will be fine unless you introduce a too low feedback pole at the inverting input C.
This comes up enough that I just…
Any VFA can be used in any inverting configuration - if you test and adjust for low phase margin should it occur - the details of your implementation matter a lot - higher R's in that kind of circuit can produce another loop pole - nothing to do with…
Other Parts Discussed in Thread: OPA847 , OPA843 , OPA846 Hello everybody,
I have downloaded the PSpice Model of OPA847 from the TI Homepage.
For the beginning I want to simulate small signal with the simple circuit shown on the Fig, 1 Page 10 in…
