The LMP90080Q is the automotive grade version with higher (150 C Max) operating temperature rating. The LMP90080 is the industrial grade version with maximum operating temperature range of 125 C. I recommend to use the LMP90080 unless you are working on a…
Hi Anthony,
In answer to your question two posts above, if you have it set up to start with CH0 and end with CH3, you will not get a conversion for CH5.
To get all the conversion results out it is best to set up your URA and when you know a conversion…
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: LMP90080 , LMP90100 Can someone help me understand the sequence of events (with code/pseudo-code examples) to achieve this? I have successfully implemented SPI comms and can write/read configuration settings to the appropriate…
Hello somebody, I hope I would get reply from somebody for this post. In the above post I ve mentioned that I have connected a RTD to CH0, another RTD to CH1. When I try to read in ScanMode 2, ADC doesnt read properly.I then, changed the register setting…
Hi,
I am facing the same problem what regu had faced.
I am using lmp90080 in my project to measure temperature using 3 wire RTD.I have connected a 3 wire RTD1 in channel CH0 and another 3 wire RTD2 to CH2.The current is given through IB1 and IB2 to each…
Other Parts Discussed in Thread: LMP90080 Hi,
I am using LMP90080 to measure temperature using RTD.In LMP90080 DS, there is a contradiction in equation for ADC_DOUT. In equation 15, ADC_DOUT = (VIN(Gain)/VREF)/2 power n and in equation 17, ADC_DOUT…
Other Parts Discussed in Thread: LMP90080 hi,
I am using lmp90080 to measure temperature using 3 wire RTD configuration.I Connected RTD1 to VIN0-VIN1,third line to the VREFP2 and RTD2 to the VIN2-VIN3, third line to the VREFP2. IB1 to RTD1 and IB2 to RTD2…
