ADS124S08: Low impedance AGND/DGND connection

Takeshi Sasaki

Part Number: ADS124S08

Hi team,

For Figure 117 at the datasheet, capacitor connection between AVSS and DGND is recommended. What value should be connected, such as 330nF or 0.1uF?

Best regards,

Hello Sasaki-san,

This will only be necessary when AVSS is not equal to GND, such as -2.5V. I suggest using a value greater than or equal to 0.1uF. 330nF would work as well.
