ADS1120: How to conduct RESET?

Part Number: ADS1120

Hi Experts,

Good day.

The device ADS1120 has no reset pin; other than sending a RESET command, may we know what's the proper way to reset it? Does conducting power cycle to digital supply only would suffice?

Thank you.

Regards,
Archie A.

    Cycling either supply to GND will initiate a reset, but it is recommended to send the reset command to reset the device.  Note that LDO, DVDD, and AVDD must all have valid voltage before the device will release from reset.  Review section 10.1 for details on power supply sequencing, and section 8.4.1 for details on the power-up reset.  I recommend sending a reset command as opposed to cycling the supplies.  Note that the reset process takes approximately 50us.  I hope this helps clarify the reset process.

    Best regards,
