Part Number: ADS1243 Hi. I've been looking at an occasional confguration issue with one of our designs that uses ADS1243 (HT version in ceramic DIL package).
In this application the power to the ADC is controlled. I previously determined that it is…
Part Number: ADS1243 Hi. Is it possible to use register(s) in ADS1243 for storing data values (while the power is connected)?
The device that I am using has only 1 analogue input and the other 7 inputs are connected to ground. From my reading of the…
Part Number: ADS1243 Hi, I'm working on an application that uses ADS1243, with 3 differential inputs. In long-running tests of 9+ hrs, random spikes are observed 3-4 times, on every channel. The spikes occur at different instances on different channels…
Part Number: ADS1243-HT Other Parts Discussed in Thread: ADS1278-HT , , ADS1282-SP Hi There
I've provisionally selected the ADS1278-HT for my high temperature downhole drilling application, but on closer inspection the gain and offset errors are possible…
Hi User5214405,
It is possible that the PDWN pin does not have a good connection. This pin must be pulled logic high for the device to convert. Also, you must have a good clock source either from the crystal or externally derived clocking source. If…
Part Number: ADS1243
Hello,
I want to interface ADS1243 with MSP432P401R processor. ADS1243 is run @4.9152MHz external crystal.ADC work on 3.3V supply. Vref+ is +2.5V and Vref- is 0V(GND). If input voltage given to ADC is 1V then what should be the…
Part Number: ADS1243 Other Parts Discussed in Thread: ADS124S08 , ADS1235 , ADS124S06 Hello,
I am using a function generator to give sine wave input of 0-100Vp and trying to see how the signal reconstruction happens at the ADC output when I am reading…
George,
Based on what I know of the ADS1243, this shouldn't happen. With an over ranged input, the digital filter accumulation should be hard limited at full scale. If the ADC doesn't limit the over ranged output to 7FFFFFh, then the burnout detection…
Part Number: ADS1243 Hello,
I have a problem with the ADC. I simply can't get it to send me DRDY pulses. When I read from registers I also get the same results (usually 255 or 0 from all registers)
This is my wiring:
I think that the wiring…
Part Number: ADS1243-HT Other Parts Discussed in Thread: ADS1243 , Hello TI Team,
What are the SNR and THD parameters of ADS1243 ?These two parameters were not found in ADS1243-HT datasheet.Customers need these two parameters. Could you share them?…
