DAC8775: DAC8775 SPI ADDRESS and DATA

Part Number: DAC8775

Hi team,

I want to use dac8875 with spi to genrerate current that is range between 0-20mA. Which order that includes address and data does ideal to generate current?

Example

1-0x03 address  - 0x0101 data (select 0-20mA)

2-0x05 address - 0x9999 data (generate 12mA)

Regards,

Emre Özçelik

  • Emre,

    First the desired DAC channel must be selected using the "Select DAC Register" at address 0x03. Following selecting the DAC channel the DAC needs to be configured using the "Configuration DAC Register" at address 0x04. Finally, data may be entered into the "DAC Data Register" at address 0x05.

    Depending on how the device is configured to receive power and reference voltage, other writes may be necessary as well.
