Part Number: LMP91051 Hi,
do I understand correctly that if the VDD and VIO pins are connected to supply (3V3) then I should see the default 1.15V value at the CMOUT pin even other pins are not connected? Since I can see 0V at CMOUT does it mean that…

Part Number: LMP91051 Good evening,
I've been implementing the application notes that can be found here , as to put together a CO2 measurements system with the help of a sensor from AlphaSense and the LMP91051 AFE from TI. The schematics for my prototype…
Part Number: LMP91051 Good Day,
I have checked the datasheet and application notes of LMP91051. If you have a look on fig. 6 (Typical NDIR Sensing Application Circuit) of the datasheet only the OUT of LMP91051 is connected to the ADC of MSP430. If you…
Hello Carmine,
Does the circuit require Lamp with ST120 for CO2 for LMP91051 for NDIR operation. Will the circuit work with only LMP91051 ans ST120,
Regards,

Part Number: LMP91051 I am very interested in your LMP91051 chip, I was wondering if you can calculate the co2 ppm from the analog output from the chip as this is not clear to me from the data sheet
Part Number: MSP432P401R I am using sensors lmp91051 and some other ti and non ti sensors along with MSP432P401R. I am having some difficulty regarding the interfacing of these sensors with msp432. So if anyone would be kind enough to guide me through…
SNAA207 shows an LMP91051 NDIR CO2 Gas Detection System based on IRC-AT Thermopile NDIR sensor.
Is there any reason, as Choongsoon asked above, why the same cicuit cannot be used for the IRC-A1 Pyroelectric sensor:
