Part Number: ADS1247 We designed a testing board with ADS1247IPW. the board can start normally at temperature higher than 0 degree C. But the board starting time was longer and longer and can't be started at temperature -8 degree C. the board started higher…
Part Number: ADS1247 Hi there,
I am trying to take a single-ended measurement with an ADS1247, but whatever I do it always returns the same value.
Here's my schematic:
I have set the registers on the ADS1247 as follows:
PGA=1
Data output rate is…

I can't find answer to my question in the datasheet. For example, I measure 0.1 VDC with gain 1 and gain 16. What's the maximum error between two values I can expect? What about all gains…

One of my customer want to know the long term drift value, like our reference have a 1000H drift ppm parameter. How about the ADS1247, do we have the Vref long term drift data? thanks…

Hi James Kiely,
The pin capacitance for this family of devices (ADS1146, ADS1147, ADS1148, ADS1246, ADS1247, and ADS1248) is captured in the IBIS model: https://www.ti.com/lit/zip/sbam010

Part Number: ADS1247 Hi sir,
can you give me some suggestion on the GND layout and VDD circuit design method that maximize the ADC performance.
1) GND layout method According to 12.1 (layout guidelines) of the data sheet, it is possible to separate the…

Hello,
I have a ADS1247 and I want to read an analog potentiometer (single channel).
So, i tied REFP0 to +3.3, REFN0 to 0V, AIN0 to 0V, AIN1 to the potentiometer exit (0V-3.3 V). I've also…
Part Number: ADS1247 Hi sir,
good day!
Because the CLK pin is not connected to DGND, if the internal clock changes to the external clock due to noise, What happens to the I/F signals (e.g. DOUT, DRDY) between the Microprocessor and the ADC?
Thanks.
