Hello,

Make sure you have pullup resistors on your SDA and SCL lines. Otherwise the circuit looks good.

Thanks,
Erin

It is pullup resistors to 2.5V/2.2K.
The DAC53401 I²C I/O voltage is stated in the datasheet as usable between 1.8V and 5.5V. Is using 2.5V acceptable?

Hi Woohyun,

2.5V is an acceptable voltage for I2C I/O. The resistors are also good values.

Thanks,
Erin
