Please can someone let me know the OP484 and OP470 intrinsic failure rates?
Please can someone let me know the OP484 and OP470 intrinsic failure rates?
Hi,
You are using single supply, -Vs = GND.
The OP470 requires 4V headroom from your -Vs which means your minimum input would be 4V in your case.
You may want to use split supply in order to accommodate 0V input.
Thanks and regards!
I ask questions about the failure mode of the OP470.
1) Does the OP470's failure modes include the case where the OP470's output terminal is shorted to V + or V-?
2) If the answer to question 1 is "yes",, what is the probability of this failure…
Good afternoon,
Some background on why I care about this: NASA GSFC launched a mission (ASTRO-H) a while back, and the front-end amplifier designs incorporated the OP470 in virtually all of the bias control. However, the engineer at the time claimed…
Hi,
While testing the model of the OP470 Op-Amp which we plan to use on a MIL PCB, I found a problem during the transient analysis.
The datasheet of this component tells us that the input bias current should be around 10nA
But in the simulations I…
Hello,
I have a question from our customer about aging of offset voltage of OP470GS.
I guess that offset voltage of OP-Amp may be affected by supply voltages.
And I think it will be categolized as quality information.
Can I have the information about fluctuation…
Hi all,
Now, our customer will start to design the PCB.
In the datasheet @ OP470 16-Lead SOIC Package,
nc (8,9pin) : "NC = NO CONNECT".
This mean, do not connect to other potential ? or no connect internal ?
The nc pin is open, or connect to…
Dear.
The two parts(OP200A, OP470) has been used in satellite system.
The power supplied to the two parts within our design are +15VDC(+V pin) and -15VDC(-V pin) at power-on state.
But, Due to some design error of the main power unit , in case of main…
Hi Harry,
You are right. With this bias current, the output offset is almost 0.7v with 100k.
So do you have any amplifiers suggestion for the two classic TIAs?
Before i was using op470. But it is too slow for this project.
Thanks.
