Hello
We are connecting the BU2508FV DAC chip to our microcontroller (PIC18F65K22), so that we can get analog outputs.
Please could you confirm that the BU2508FV DAC chip should not be connected to either the SPI module , or the I^2C module of the microcontroller?
It appears (would you agree) from the datasheet that one simply clocks in the data and then the address (output channel). This transfer of information into the DAC chip should be done when the LDAC pin is low, and the transfer of data is complete when the LDAC pin goes high….would you agree that no SPI module or I^2C bus is necessary for this?
