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…

Part Number: REF6241 Other Parts Discussed in Thread: ADS1285
Hi team,
I use REF6241 as a reference for several ADCs(ADS1285).
AVDD3=5V,AVSS=-2.5V,VREFN and VREFP connect to N/P pins.
I measured VREFN and VREFP, found out VREFN = -2.5V but VREFP=0V
According…
Part Number: ADS1282 Other Parts Discussed in Thread: ADS1285 Tool/software: Hello,
I have some questions about the calibration procedure shown below.
I want to further understand each command and their role.
1) Why is SDATAC first sent if it is followed…
Part Number: ADS1285EVM-PDK Other Parts Discussed in Thread: ADS1285 Hi team,
I was looking at the ADS1285-EVM circuit, I found a functional circuit in the ADC front end (picture below). If I'm using a single-ended input, what does this circuit do, filter…
