Part Number: LMP90077 I have a batch of prototype board using the LMP90077, eight boards draw minimal power but two are drawing about 20mA but still operate correctly otherwise (the LMP90077 is drawing the current).
The data sheet says to leave the…
Hi again,
i had to pause my LMP90077 project for a while but a few days ago I contiuned with this project.
Now I am able to do a offset and gain calibration with feasible and reproducibly results.
Therefore I have to preload the SCAL_GAIN register…
Other Parts Discussed in Thread: LMP90077 , LMP90100 Hi,
I have questions about the LMP90077.
1. The Resolution is 16 bit, which makes 0 - 65536 values. I want to use the device single ended. Now the datasheet Figure 71 shows that the MSB seems…
Thanks for your suggestion, it probably would not work.
Looks like I'd missed the minimum common mode voltage of 400mV when using the x16 FGA.
With a common mode half supply voltage (2.5V) and 50mV differential, it all works as it should.

Other Parts Discussed in Thread: LMP90079 I am using the LMP90079 specifically, but this question applies to the whole series.
On page 5 of the datasheet, it says "Leave the thermal pad floating". However, the reference design on page 60 shows the thermal…
Other Parts Discussed in Thread: LMP90077 Dear Sir
Good days,
May we check if LMP90077 example code?
for example, how to correct set up GPIO direction?
Best regards,
Bogey
