ADS1113: ADS1113 Noise Performance Impact with VDD=5V

Filipe Rubinstein

Part Number: ADS1113

Hi all,

Section 8.1 of the ADS1113 datasheet lists the noise performance of the device for a VDD=3.3V. How would the noise voltage change for a different VDD=5V, if any?

Thank you for your time and I hope back from you all soon!

Hello Filipe,

Across voltage the difference in RMS noise may increase by about 5uV between 2V VDD and 5.5V VDD at high sampling rates. You can see this in Figure 15. Noise vs Supply Voltage in the datasheet linked above.
