Part Number: ADS1147 Tool/software: Here are 2 issues we found, during the long-term testing of the resistance detection function
1.For the registers configured through SPI, when repeatedly reading them, there is a probability (occurring about two or…
Part Number: ADS1147 Other Parts Discussed in Thread: SN74LVC1G125 Hi Team,
When using uC communicate with 3 ADS1147 devices using the same SPI with different CS pins for synchronous sampling , the MCU performs to read the data from the specific ADS1147…
Part Number: ADS1147 Hi Team,
The SPI SCLK is from uC is around 2.1M-2.3M(477ns), which works well for now to communicate with ADS1147, but the min SCLK is 488ns from the datasheet. If there is any risk to use this frequency?
Thanks a lot

Part Number: ADS1147 Tool/software: Hi expert,
A strange thing happened,
ADS1147 can only output an integer voltage value, for example, the actual voltage is 11.458MV, the ADC value is 2816 @PGA is 16 with SPS 20, the calculated voltage is 11.000mV…
Part Number: ADS1147 "Send 16 SCLKs to read out conversion data on DOUT/DRDY;" I took this part in ADS1147 datasheet page number 65 pseudo code. Is the SCLK signal sent to the DIN pin using SPI? Or SCLK pin of ADS1147 normally? This is not clear to me…
Other Parts Discussed in Thread: ADS1147 I need ADS1147 and CC2640R2 microcontroller using the master and using spi to get the data in the slave and the code and its details.please help me
Part Number: ADS1147 Other Parts Discussed in Thread: ADS1247 Dear Specialists,
My customer is considering ADS1147 and has a question about input channel crosstalk.
I would be grateful if you could advise.

Part Number: ADS1147 Dear Sir/Madam,
In our application we are using ADS1147 for measuring temperature from Pt100 sensor in a 4-wire measurement system. Our micro controller code is as per the pseudo-code example mentioned in page 65 of ADS1147 datasheet…
Hi Yang,
The ADS1147 is 16 bits and cannot directly perform single-ended measurements since the PGA is differential with a common-mode voltage requirement. Instead, you could set the negative input to mid-supply, and swing the positive input around…
Hi Micco,
Welcome to the E2E forum! The ADS1147 is an oversampling ADC that samples at the modulator rate and then uses an FIR filter to output the data at the selected data rate chosen in the register settings. The modulator rate changes depending…
