Other Parts Discussed in Thread: OPA1632
Hi,
I am currently working on a DAC reconstruction filter using the LME49724 after coming across massive issues using the OPA1632.
The LME49724 worked fine on the first prototype.
I ordered some more LME49724s from mouser for the second prototype, using the exact same circuit and the same layout. The only change is that a thermal pad was added to the footprint.
Unfortunately, the LME49724 behaves normally for a short period of time (seconds) and then goes completely crazy; meaning it draws about 4 watts per rail and does not produce any output.
There are no signs of oscillation visible on the output.
Of course I have tested for shorts and tripple checked the component values, but I cannot find an explanation for this phenomenon.
Any help would be appreciated.
