Part Number: LMP90100 When reading data from AFE using SCAN_MODE1 or SCAN_MODE2 , all channels in the range FIRST_CH to LAST_CH get scanned, but not in the expected order. For example, in order: (FIRST_CH + 5) through (FIRST_CH +4).
Part Number: LMP90100 Other Parts Discussed in Thread: ADS124S08 I want to read values from 2 RTDs using LMP90100 AFE software. But it cannot separate the current sources as two different channels. If I make another connection like 3-Wire RTD using…
Part Number: LMP90100 I was wondering what the acquisition time or integration time of the AFE is based on the ODR. Do lower ODRs provide more acquisition/integration(/averaging) proportional to the rate? Something else? Is there any variation or description…
Part Number: LMP90100 I try to program the LMP90100 with the help of the PIC24F series. I use SPI as a type of communication. However, I have a problem with the fact that the examples for LMP90100 are already written on MSP430. Where can I find the LMP90100…
Part Number: LMP90100 Hello!
We are using the LMP90100 in our precision pressure measuring instrument. Three pressure sensors are connected on three differential channels of the LMP90100 respectivly.
At some of the devices, there is a great disturbance…
Hi Alex,
thank you for your answer!
The ApplicationReport SNAA074B (LMP90100TrueContinuousBackgroundCalibration) describes the backgroud calibration for the offset of the LMP90100 with the words "An important assumption behind this offset calibration…
Sachin,
I'm not sure what is the problem at this point. Are you able to look at a logic analyzer output for the this device? What result from output data do you get stuck on? I may help to have the full output run from the device reporing back the…
Part Number: LMP90100 Hello everyone,
I'm currently working on a project that involves the LMP90100 AFE. I've managed to make it work with the MCU and configure it. However, i wonder if anyone has tried this circuit with four RTDs(no matter for the…
Part Number: LMP90100 Hi,
When you configure the LMP90100 to scan multiple channels by setting CH_SCAN to 0x83 (multiple channels, starting from 0 with 3 as last channel, repeated), what is the correct way of knowing which channel was sampled when you…
Part Number: LMP90100 Hello,
we are using LMP90100 since 2011 (former National Semiconductor) with introduction in one of our devices in 2012 but now we are facing a problem we have never seen before:
we are working with ScanMode0: single-channel…
