DAC6571: Readback of DAC Register

Joe Menzie

Part Number: DAC6571

Hi TI Team,

Does the DAC6571 support the ability to readback the DAC register via i2C? And if so, are there specific register addresses that need to be used to find the MSB and LSB?

Thanks!

    Hello Joe, 

    I2C is bidirectional communication protocol. In order to communicate with the device, master needs to sed a byte. First 7 bits is the address that could be configured by A0 pin. The last bit of a byte is R/W bit. If you send 0, the device would be in the write mode hence the following data would be recorded as a data in the device internal register. If you send 1 it is a read command, and device will read back the content of its register. Please refer to page 13 and 14 of the data sheet for more detailed description and timing diagram. 

    Did this answer your question? 

    Thank you,
