Part Number: ADS1285 Tool/software: hi Sir
we would like to design a meter for thermocupler, old design is use ADI/AD7780
We would like to design the next gen product, spec as below
did you have any advise?
thanks

Tool/software:
Hello,
we have been trying to figure out why a board featuring three ADS1285 ADCs is absorbing a lot of current from the negative supply. Our circuit has bipolar power supplies for the analog section. ADS1285 AVDD1…
Part Number: ADS1285 Tool/software: Hello. I am designing a board that must acquire the signals of some geophones and I want to use the ADS1285 analog-to-digital converter. In the datasheet I can not find the indication of the input impedance of the…
Hello Xingwitt,
I assume you are using an external function generator, since the maximum output voltage of the DAC1282 is +/-2.048V when using the 4.096V reference included with the EVM.
I am guessing that you have a single-ended connection to the EVM…
Hello Xingwitt,
The ADS1285 uses a dither function to reduce idle tones in the lower frequency passband. This dither function is basically a 0.25Vpp square wave that is added to the input signal. This dither frequency is removed when using the FIR+SINC…
Part Number: ADS1285 Other Parts Discussed in Thread: ADS124S08 Hi everyone,
I'm trying to use the ADS1285 for temperature control of my device, but I can't find anything on the internet (because he's new in the game ?). My purpose is to send the data…
Part Number: ADS1285 Datasheet section 9 describes power supplies and the need for bypass caps between AVDD1 and AVDD2 and AGND. For single-supply operation, AVSS is connected to AGND. However, for dual-supply operation, AVSS is -2.5v but there is no recommendation…
Part Number: ADS1285 Other Parts Discussed in Thread: ADS1282 Hi, we make some equipments with ADS1285, all of them are synchronized by the GPS PPS, while we found some of the units and some time, the data recorded is about 63 samples prior to the other…
Hello Alec,
Thank you for your reply. I have thoroughly reviewed the datasheet.
Could you please recommend suitable evaluation boards along with your simulation results.
We plan to purchase ADS1285EVM-PDK Evaluation kit.
As Mark suggested, we have also…
