Hello Maged,
Thank you for your patience. We reviewed your design and requirements, and have a few comments and suggestions.
Looked into the waveform generator, and it has a voltage output between 38mVpp to 0.65Vpp with a max frequency of 12.5MHz with…
The unit started producing negative voltages when I cut back on the flying capacitance. I have no explanation as to why the output was positive instead of negative with an extra uFd+ of capacitance.
The accuracy of the negative output voltage is a question…
Part Number: TLV9161-Q1 Other Parts Discussed in Thread: OPA2607-Q1 , OPA355-Q1 Can you suggest high side current sensing op amp with higher band width (above 4MHz) and higher common mode voltage (above 12V ); Supply voltage is 5V(+V)
and. now i regonized to be difference current input nosise charaterisctic between bioplar and FET. other referecens usually used bioplar type of opamp for noise analysis. but i want to know FET type of opamp for noise analysis. do you know how to revise…
Hi Kai Klass69:
I add circuit.
Regarding integrator and LPF, I've not decided value of resistor and capacitor yet.
I thought my design, OPA355 can't output negative voltage.
Add -2.5V to Vs- of OPA2810 and OPA355 is just to satisfy minimum Vs…
Other Parts Discussed in Thread: OPA355 , OPA2355 , LMV861 , LMV881 Hi I have been using Opa355 in my current products with good success. (Shipping in several K units). It is used in a Tia with 8M gain at 1MHz signal.
I recently started a new design and this…
Other Parts Discussed in Thread: OPA2690 , OPA355 Hi Sir,
I need help using the filter design tool!!!
My customer request is the center freq. is 3.5MHz, the pass bandwidth is more than 4MHz.
However, I cannot use the filter design tool to get the suggested…
Other Parts Discussed in Thread: OPA355 The OPA355 datasheet has a of recommended Rs versus Cload. In my ignorance I do not understand the implications of this chart. I was hoping someone here could provide some insight.
The chart shows a smaller value…
Other Parts Discussed in Thread: OPA355 In the OPA355 datasheet there is a graph of gain flatness versus Rf. The graph indicates that the amp has more peaking with higher Rf. Why would this be? For most CFAs the opposite is true. Is this an error?
Part Number: OPA356 Other Parts Discussed in Thread: OPA355 , OPA627
I design a TIA with OPA356 and SFH250V(Photodiode):
Since maximum photocurrent of SFH250V is 100uA,
and I hope higher gain of photocurrent for my usage.
Thus, 100k Rfb is necessary after…
