Hello everyone,
We have lost the ability to change the gain on the LMH6401. When we read the gain at '0x02' it appears to always be clamped at '0x00' which corresponds to maximum gain.
When I try to write a new gain with '0x0B' (for example), it shows the feedback of '0X0B' when '0x02' is read but when I read it again, it's set back to '0x00'.
We have seen this before with the LMH6401 EVAL GUI and I'm not sure how it fixed itself but a few power cycles and it was back up. Not the case with the our actual HW implementation.
Any suggestions?
