Thanks. Yes, I found the ADA4096-2 and the ADA4177-2. The ADA4177-2 has lower input bias current but the packages are larger than the ADA4096-2 in LFCSP.
The OVP feature prevents damage in my example but I'm not sure whether operating within the OVP window…
We have purchased ADA4177 IC from Element14 , QTY 1000 for company requirement.But frequent failure observed for same IC in our PCB where we are using IC ADA4177 (at location U3 only, though U11 is also same IC). We have done failure part analysis at…
Can I use the opamp ADA4177-2 in single supply operation?
It is specified for +/- 15V.
Can I apply 28V dc to positive supply rail V+ and ground V-
I plan to bias the input to the chip at 14V dc.
the best way to protect the input from the OVP is to use ADA4177-2 since it has an integrated input protection during overvoltage conditions.
This is a simple circuit intended to replace any dual op-amp in dip 8 pkg.
Short question is , is there any tendency on this part (ADA4177-4) to self oscillate? Probably not but wanted to ask.
I have a new layout that is self oscillating…
I'm surprised it is doing anything.
-- You need at least 5V across the part to wake it up
-- It is not RR input; you need to stay at least 1.5V away from either rail.
Try an ADA4084-2 or an ADA4528-2
For the LMC662,, you could also look at:
Thank you for your answer.
We weill confirm ADA4177.
Any op amp can be used on split supplies or single supply. See thread:
The ADA4177 is designed to be robust when powered from a variety of power supplies. With an excellent power-supply rejection ration (PSRR) of 145dB, it can tolerate significant supply noise. When calculating the total precision of a signal path, be…
