Please ask about the absolute maximum ratings listed in the data sheet.

The digital input terminal, which is the SW terminal, is 0 V or higher.
Isn't it more than -0.3V?

I have a question about the AD5246.
How long will it take for the AD5246 to start I2C communication at the shortest time after power supply VDD rises?
I write the resistance value by I2C communication.

Best regards

Hello,

Absolute maximum ratings specify that the AD5246 digital input VIL is 0V.
The digital inputs are protected by parallel Zener diodes.
Is it possible to input GND-0.3V to the digital input?

Best regards,

I would like to use a variable resistor in my design, and I am not sure if there is any differnce between using AD5247 and AD5246.
