Can the EVM DC2692A-A of LTC2662 be used without the DC590 controller?

    Thread Summary
    
                The user inquired about using the EVM of the LTC2662 without the DC590 controller and asked if it's possible to connect an Arduino or ESP-32 to the SPI pins. The engineer confirmed that other SPI-compatible interfaces can be used, provided the timing specs of the DAC are met. The J1 header pinout was requested, and the engineer provided a diagram and suggested checking the full EVM schematic on the DC2692A-A product page.

    Hi, planning to use the EVM of LTC2662, can I use the EVM without the DC590 controller? 

    Is it possible to connect an Arduino or ESP-32 to the SPI pins and control the DAC instead of using the DC590?

    Thanks
