Part Number: ADS1256 Other Parts Discussed in Thread: REF70 , PGA280 , ADS127L11 , ADS1262
Hello,
1. Introduction
My application requires high linearity ADC. I've looked at TI product portfolio and I have chosen ADS1256. According to datasheets…
Part Number: INA321 Other Parts Discussed in Thread: LMP7721 , , REF70 Hi, TI.
I designed a trans-impedance amplifier circuit using a LMP7721, INA321 and REF2030.
The INA321 was used to amplify the fluctuating voltage signal based on 1.5 volts.

Hi Himanshu,
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…
Hi Lhagva,
Lkhagvajantsan Damdinsuren said: 1. Please recommend me Vref voltage for ADC ADS1285? I think 4.096V from external reference chip might be good point.
Since this is 32bit ADC, you would need to have ultra precision 4.096Vref for the application…
Hi Dennis
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…
Hi Eric,
We have some great selection of voltage references in the link below. For instance, REF35 , REF50xx , REF60xx , REF70 and many other low cost, low noise, very low drift precision voltage reference for the ADC application.

Hi Newton,
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…
Takahashi-san,
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…
Part Number: ADS1256 Other Parts Discussed in Thread: OPA189 , OPA2189 , OPA350 , REF70 , REF6025 , REF7025 I am designing a calibration board for use with the ADS1256 and a 12-bit MCU SAR and I would appreciate some advice: If I understand correctly…
Hi Nishant,
Nishant Gupta said: Is voltage stability measured as peak-to-peak output voltage variation over a specified time interval?
TI does not have a single "voltage stability" specification for voltage references. We specify our voltage references…
