The output is oscillating. Can you please confirm it on the scope.
You are exxeding the output capacitor spec (57pf) and overall ESR. Can you please remove R29 and C37 and check the output.
Please refer the layout recommendation given at page…
Please take a look at our high precision REF70 family. This should provide higher initial accuracy, and better tempo and long term drift. Hope that helps.
I wouldn't recommend looking at each individual component, I would look at each individual signal chain. As such you will need to calibrate each channel of the ADS131M04 to ensure highest accuracy.
I recommend taking a look at the REF70…
Thanks for the post.
You can use the ADS1299 with different external reference voltages and not limited to 4.096V. The preferred reference voltage is 4.5V in order to meet the datasheet specification for noise and dynamic range. The ADC input…
Part Number: ADS1256 Other Parts Discussed in Thread: REF70 , PGA280 , ADS127L11 , ADS1262
My application requires high linearity ADC. I've looked at TI product portfolio and I have chosen ADS1256. According to datasheets ADS126x…
Part Number: ADS1282EVM-PDK Other Parts Discussed in Thread: ADS1282 , ADCPRO , ADS1261 , OPA1632 , ADS1262 , REF70 Hi,
We bought a ADS1282 EVM PDK kit. Kit is working fine.We are using adc pro software for configuring and analysing ADS1282 EVM PDK kit. We are…
We currently don't have any products with such low long term drift. Depending on the calibration interval and the temperature range of operation one of the following products may be suitable: REF7025 (in Ceramic) about to release https…
One point of clarification here: the ADS1256 does not have an internal reference. You mentioned "less exact 2.5V reference inside the product", and I was not sure if "product" meant the ADS1256 or the board you are designing, so I just wanted…
