Yes I can get some LT10xx parts.(or let me know of some part and i can check)
I also looked up OP777,727,747 checking whether i can get them.
AD620 is the one i can get easily and seems AD is well stocked up.
I can use a dual supply if OP07 has to be used.
Its just that, the specific part LT1677 i am not able to get
@Rajneesh
I looked up Austria Microsystems and found
THIS page for LED drivers.Can you point out which ones the closest?
Thanks for the support
