A have two channel thermopile HTS E21 http://www.heimannsensor.com/Datasheet-3a-Dual_Quad_rev2.pdf . Can be used "IN" and "CMOUT" pins of LMP91050 as differential input? I plan to connect the pin No2 of thermopile to the pin "IN" and…
Other Parts Discussed in Thread: LMP91050 To all,
I'm evaluating the lmp91050 dev board with the spi04 board, I'm getting quite a bit of noise on the output.
Using a thermopile on U4.
How can we reduce the noise?
Thanks,
Bob
Hi Nibi,
I can't make a recommendation based on Energia libraries, but it looks like the HDC1080EVM has provisions for separating the section with the sensor from the EVM and using an I2C interface to communicate from a host like the CC3200. Check out…
Dear Aravind,
We reviewed the schematic, and our comments are the following:
In the LMP91051, the analog ground and the digital ground are internally connected;
It is ok to combine the three AFE’s CMOUT pins using resistors, but please modify their value…
Other Parts Discussed in Thread: LMP91050 Hello,
I found LMP91050 when I looking for the amplifier for photodiode.
I don't know about the LMP91050 details.
Who can tell me whether can I use this IC with photodiode?
Thanks in advance,
Cheol Lim
Other Parts Discussed in Thread: LMP91000 , LMP91050 Hi,
I'm reading about TI AFEs for gas sensors and I have some doubts about.
In particular, I'm looking at gas & NDIR afes.
For LMP91000 :
Instead of adding an external EEPROM for every…
Other Parts Discussed in Thread: LMP91000 , LMP91050 , LMP90100 Hi to all,
I'm using the LMP91000 and I can't find the Methane sensor in the software. Do I have to configure the soft to use the methane sensor ?

Hi Tom & aale,
We are currently trying to get this resolved. You can see the LMP91050 but not the LMP90100,LMP91000 or LMP91200 from Webench tutorial.

Hi
not sure about your total set up, but if you have a µC in your system and your coil can be moved to a common mode offset, have a look to the LMP91050. The advantage of this part is, it is a two stage amplifier, with pretty low input bias. Most important…
