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…
Part Number: OPA657 Other Parts Discussed in Thread: OPA858 Hi,
I'm testing following circuit using OPA657 as TIA.
And I found when detecting small light pulse (gaussian wave), it works well.
But when detecting large pulse, when the OPA657 get saturated…
Part Number: OPA657 I've both simulated and tested a TIA cuicuit using OPA657. this circuit is made for a 30pF PD
simulated result is here
2layer TIA circuit is made ,layout is close to the evaluation board. I make a interface circuit (C1=4.7nF,C2=30pF…
Part Number: OPA657 Hi
I'm considering the TIA design with a feedback T network.
Target gain is around 120dB and BW shall be larger than 1MHz.
I've almost finished it and hope that you will take a review.
BW:
Stability:
And what I want to get…
Part Number: OPA657 Other Parts Discussed in Thread: OPA857 Hi, support team
My customer has the questions as follow:
1. Could you provide OPA657 gain's temperature characteristic (0℃~40℃) ? (drift value across the temperature or graph vs temperature…
Hi Follin,
Follin Ju said: But when I touched the metal part, the noise shown on the Scope decreased from 15mVp-p to 6mVp-p - the 22kHz noise seems dispeared.
By touching the shield you have transformed your body from an EMI radiating antenna into a shield…

Hi,
I'm designing a four channel optical detection front-end with OPA657 and THS4541.(connected to following ADC3683)

Part Number: OPA657 Hi team,
If customer use OPA657 as a single supply(+12V) and the DC bias to 2.6V, the positive voltage of power supply would be 9.4V. This exceeds the threshold of absolute maximum rating of supply voltage.
Is my understanding correct…
