Part Number: ADS1284 Hi to all users! I'm planning to design ADC for seismic purposes. Taking a look to ADS1284 datasheet I can see I can power ADS1284 with dual supply +/-2.5V. Datasheet:
AVSS = from -2.6 to 0.0 [Volt] AVDD = from AVSS +4.75 to AVSS +5…
Part Number: ADS1284 Hi Team,
Have found that the datasheet shows the PGA noise (V/sqrt(Hz)). However, we also need the specification of the noise BW of the ADC itself. We have checked that the filter is based on a SINC5. But, it never shows the value…
Part Number: ADS1284 Other Parts Discussed in Thread: 4213 , 4428 , 4430 , 4460 The analog input is shorted, but the data looks strange, the offset is very high at the begining, but lower and lower, after about 40 seconds it get back to normal.
Please see…
Part Number: ADS1284 We are using ADS1284 for data recording, each time i turn it on, the DC offset is randomly either -40uV or 77000uV, could you please help what's the problem, thanks.

Hi, when we are using the internal offset and gain calibration for ADS1284, each time it runs with dfferent results. Could you please help to check the code as bellow?
Part Number: ADS1284
Hi, please help to check is there any problem for the calibration procedure.
1. Turn on the powers of ADC
2. Configure the registers for sampling rate, HPF filter, PGA gain, mux set to 010 and OFFSET set to 11.
3. Run the OFFSET…
Part Number: ADS1284 We are currently evaluating the ADS1284. We felt that the output stability of the ADC was higher than expected, so we enabled the Internal Short feature. However, the output stability of the ADC did not improve. Please give me some advice…
Part Number: ADS1284 Other Parts Discussed in Thread: LM27762 , REF6250 We are evaluating ADS1284 and during our tests, on our prototype board, we have noticed that while we achieve very similar SNR (RMS noise) numbers to the datasheet, we are seeing a…
Part Number: ADS1284 Other Parts Discussed in Thread: LM27761 , TPS7A05 My customer is using an ADS1284.
Presently, he is using an LDO (TPS79325DBVR) to generate the +2.5Volt rail from the 3.0Volt rail that I have for the digital side of the electronics…
