However, customers…
Part Number: OPA657 Other Parts Discussed in Thread: OPA818 Until today we used in our production part "OPA657N B " - we would like to know if "OPA657N" is the same part with exactly the same parameters? Meaning FFF?
For what stands the…
Part Number: OPA657 Other Parts Discussed in Thread: OPA818 Hi,
I see that the parametric differences between OPA657N and OPA657NB were omitted from the REV F. of the datasheet,
from what is seen in REV D. and E., and this change does not appear in…
Part Number: OPA657 Hi Team,
We have a customer using OPA657 as the transimpedance application as below. The diode is a APD that need Vb supplied up to 50V. For this design, it is ok to use the circuit directly? If not, any other circuit recommended or…
Part Number: OPA657 Other Parts Discussed in Thread: OPA818
Hi, I'm using the OPA657 as transimpedance amplifier(TIA), and also reading datasheet of OPA657.
I find it states 'OPA657 has 1.6GHz Gain-Bandwidth Product(GBWP)' and also figures open loop…
Part Number: OPA657 Other Parts Discussed in Thread: OPA357 Hi TIer
My customer want to find a chip which performance like OPA657U and rail to rail because OPA657U is not rail to rail.
Could you give me some suggestion?
Hi Seongjin,
The OPA847 is not intended for a gain that high. However, the OPA818 is a good substitute for the OPA657 because it has a similar performance but just a different pinout. I have attached a TINA schematic so you can compare the output of…
Part Number: OPA657 Other Parts Discussed in Thread: OPA818 , i require OPA657N for ongoing project.
the requirement is in thousands.
can you help me out with the sourcing of component?
Hi Kai,
kai klaas69 said: There's one more issue: I think that some of your components are too large. I mean the feedback resistors and half of the decoupling caps
- I used Susumu RG2012P-155-B-T5 , it's 0805 footprint. I read somewhere that using 0805…
