AD7780 Voltage Sequencing and Analog Input Voltage

Question asked by bellkev on Oct 25, 2013

Hello,

 

I'm wondering if the AD7780 can use any voltage power on/off sequence without damage. I'm also wondering if voltage can be applied to the analog input pins while all or some of the power supply voltages are not powered.

 

Pins in question: AVDD, DVDD, REFIN+/-, AIN+/-, what are the limitations for sequencing voltages applied to these pins?

 

Thank you,

Kevin
