ADC081C021: Pull-up resistors for I2C

KOJI HARADA
Prodigy 20 points
Part Number: ADC081C021

Tool/software:

Its datasheet says that the pull-up resistors for SCL/SDA are pulled to the same voltage potential as VA, but they seem to be able to work with up to 5.5V even if AV is 3V as described in Operating Ratings.

Can ADC081C021 work with 5V I2C while 3V VA?

    Hi Koji,

    Yes, the ADC081C021 will operate as expected with a 3V supply voltage while its digital input pins are driven with to 5V logic levels. This is explicitly described in the datasheet operating ratings section:
