ADS8634: Minimum HVDD and HVSS values

Phil Harju

Part Number: ADS8634

Tool/software:

Can I connect HVDD to 5 volts and HVSS to 0 volts for a 0-5 volt range with a max AIN of 3.3 volts?

Hi Phil,

As noted in the original post, yes - you can tie HVSS to GND when converting only positive input voltages.

What about 5 volts to HVDD? This does not meet the 10V < HVDD - HVSS < 30V described in the datasheet.

Hi Phil,

I missed that initially - you can do 0 and 10V or +/-5V for HVSS and HVDD.
