Part Number: ADS8866
Hi team
Does ADS8866 malfunction in the following sequence?
Power-Up : 30 msec after AVDD(3.3V) and DVDD(3.3V) rises, REF (5V) start rising.
Power-Down : After AVDD(3.3V) and DVDD(3.3V) decreases, REF(5V) gradually decreases over about 500 msec.
Do we need to control the REF sequence? Is it possible to keep the reference voltage power on regardless of the VDD status?
best regards
