Part Number: ADS1284 Tool/software: I previously asked a question here: ADS1284: High Frequency performance at high gains
I did missed the response from Keith Nicholas who stated:
The PGA frequency response should be flat for all gains out to 1600Hz…
Part Number: ADS1284 Tool/software: We use the ADS1284 in some of our products.
An end-user has stated that they have noticed an unusual drop-off in high-frequency response for higher gain levels.
I have asked the end-user for more information, and…
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…
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…
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.
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…

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…
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…
