Part Number: OPA2675 Hi , Experts
I have design above circuit to test the basic function of OPA2675,
But when I supply ±6V or 12/0V power, it will get hot in seconds and the AOUT+ output nothing!
it's can't find any wiring error or short circuit…
Hi Nikhil,
I don't see any issue in the information you shared except the layout is not good. Not connecting the thermal pad will give you bad thermal performance (higher thermal resistance).
I recommend using pour and multiple pins instead of using…
Hi Fujiwara,
Yasushi Fujiwara said: Does it mean this device can be insertion/extraction of RS-485 cable even if equipment are powered on.
It is possible for the device to be plugged into a live bus. But the system needs to be designed properly to ensure…
parryh said: It looks like the header always gets placed right after the processor exception (reset vec, etc.) interrupt table and before the rest of the interrupt vectors (assuming the bytes 2D E9 onwards are the interrupts vectors).
Hi Parry,
I think…
Part Number: UCC28070A Hello,
The project we're working on is a Power Factor Corrector, PFC board for a customer that uses them to power ozone-reactors for industrial washing machines.
More specifically, it is an interleaved boost PFC where the logic…
Part Number: LMR36006-Q1 Hi,
I am having an issue with the part LMR36006FSC3RNXTQ1.
I am using it to lower the 24VDC voltage to 3.3V and 0.15A.
I am measuring a case temperature of 70C with ambient temperature of 25C.
I have looked into the Flip Chip temperature…
