Part Number: ADS1218 Other Parts Discussed in Thread: ADS1243 We are using the ADS1218 (and the ADS1243) in both chips there is a /PWDN pin that we use to shut down the part to conserve power. My question is how long after raising /PWDN is the chip ready…
Part Number: ADS1218 Hi All,
IN ADS1218, user is suppose to read the data when DRDY goes low. Is it mandatory to read this data in every DRDY low cycle? Let us say I read the data after few DRDY cycles, will I get the correct data i.e. the data of the…
Part Number: ADS1218 Hi Team,
Could you please let me know the maximum value for the Fdata of ADS1218Y.
From the datasheet , Fdata = (Fosc)/(mfactor*decimation ratio);
Maximum Fosc = 5MHz.
Minimum mfactor = 128, decimation ratio = 20.
By calculating…
Part Number: ADS1218 Hi Team,
I am using ADS1218Y with a external clock of frequency - 2.4576MHz/ Amplitude - 4Vpp from a function generator. I was able to successfully use all functions like registers,ram, flash ADC,DAC etc
I want to know the minimum…
Part Number: ADS1218 Hi,
I have few queries regarding the operations of PGA and calibrations in ADS1218,
1) Does PGA is used only for maximizing the input resolution? say 40mV for PGA =1 and 70nV for PGA = 128. If it have any other purpose, please…
Part Number: ADS1218 1. If I give 1 V differential input at ADS1218 with Vref = 2.5; PGA = 2; will I get 2V as output(i.e 24 bit dout data points to 2V) ?
2. What differential input can be given while issuing selfcal commands?
Hi Van, I am also trying to use ADS1218 with MSP430. However, I nearly can't find any code example for ADS1218. Can you send me the code for ADS1218 if it is convenient for you. Thank you very much. My email is wt20094324@163.com
Hi Shinu,
There are a couple of things that can affect reference output. One is the frequency of operation and the second is loading of the reference. Do you know if the customer has measured the reference by looking at the output with a scope? We would…
Hi Tanweer,
I apologize that I have not responded sooner. It is often easier to see what might be going on using the raw codes from the ADS1218 as opposed to the converted result as this will eliminate any confusion with respect to data conversion error…
Part Number: ADS1218 Hello all,
I'm working on a design equipped with ADS1218 and I need some hints to make it strong against EMC / EMI events.
Is there any TIDesign about this topic ?
Thank in advance
Stefano
