GP8413 A question about the application of a DAC chip [Copy link]

I am currently working on a voltage-to-current embedded project, using a DAC chip, GP8413. I have some questions about the application of this chip:

1.GP8413 uses the I2C interface to linearly convert two analog voltage outputs of 0-5V/0-10V. How do the two outputs OUT0/OUT1 correspond to 0-5V/0-10V?

2. Pin 10 V5V, the chip manual says "internal LDO, 5V output", what is this 5V output used for?

3. The hardware address of the chip is set by the three pins A2A1A0. If one of the pins is to be set to a high level, should it be connected to the power supply voltage or the 5V output voltage of pin 10?

4. Input I2C signal high level: 2.7V-5.5V, so can the SDA/SCL of IC2 signal be pulled up with 5V?

1.GP8413 uses I2C interface to linearly convert two analog voltage outputs of 0-5V/0-10V. How do the two outputs OUT0/OUT1 correspond to 0-5V/0-10V? ------See the data sheet.

2. The chip manual says "internal LDO, 5V output" on pin 10. What is this 5V output used for? ----- For other microcontrollers and other devices

3. The hardware address of the chip is set by the three pins A2A1A0. If one of the pins is to be set to a high level, should it be connected to the power supply voltage or the 5V output voltage of pin 10? -------It is the 5V output voltage of pin 10.

4. Input I2C signal high level: 2.7V-5.5V, then can IC2 signal SDA/SCL be pulled up with 5V? -----Yes, you can use the 5V output voltage of pin 10

Thank you for your reply, it solved my doubt.
