Part Number: ADS114S08 Dear TI Expert,
In the scenario of a three-wire high side RTD circuit with two iDAC current sources, if we would like to filter out 50Hz interference signal, apart from design the cutoff freq for input differential RC circuit part…
Hi Tim,
The internal temperature measurement is a calculation and you are measuring with an IR thermometer that has an accuracy of +/- 2 deg C. Also, it is not a trivial task to measure such a small area using an IR thermometer with a ratio 8:1. The IR…
Part Number: ADS114S08 Other Parts Discussed in Thread: ADS124S08 Hi Team,
do we have specifications for the inputs / MUX of ADS124S08/114S08 in off-state? We want to understand for our application how much crosstalk we have to expect in a multi channel…
Part Number: ADS114S08 Other Parts Discussed in Thread: ADS114S06 Hello ,
We followed the configuration of Multiple Two-Wire RTDs (Figure 15) in ours design. Also, as explained in the datasheet chapter 9, it is written: "As described in the Functional Block…
Part Number: ADS114S08 I have implemented this ADC as part of a data collection system which reads an array of 64 RTDs. Signal switching is done mostly with external multiplexers but I do cycle through 4 sets of ADC inputs, switching the INPMUX between…
Part Number: ADS114S08 Hello,
I am looking for some clarification regarding the calibration commands for the ADS114S08 ADC.
1. Does the SYOCAL command perform the same function as the SFOCAL with the only difference being SFOCAL shorts the inputs to mid…
Part Number: ADS114S08 I am writing this post in hopes that someone will have experience driving the ADS114S08 using an STM32F4 Nucleo board or a similar STM board.
I have had no success in establishing reliable communication with the ADC.
Here is the…
Other Parts Discussed in Thread: ADS114S08 Dear TI Expert,
We have an application that requires to detect 4~20mA signal. We plan to use 10ohm resistor of high precision to transfer to 40mV~200mV voltage signal. And we are thinking of using PGA inside…
Part Number: ADS114S08 Other Parts Discussed in Thread: ADS124S08 as mentioned in ADS114S08 datasheet, the increasing of OSR, will help to improve the noise performance of ADC
but in its datasheet noise value table, the noise rms and peak to peak value…
Part Number: ADS114S08 Dear TI Expert,
We have an application of detecting 4~20mA signal. So far, we've designed to use a resistor of high precision and a non-inverting opamp to amplify the signal. which is then fed into ADS114S08's analog input.…
