No output on dac device

Category: Hardware
Product Number: ltc2668

'm trying to control a LTC-2668 dac device, by sending data to an stm32 and using  the spi interface. The dac opperates on mode 00 and spi commands are 24 bits long. The chip select pin is manually toggled

The thing is that even though the STM produces the output signals, i get no output on the dac device.
Here are some pictures of the produced signals( captured on ananalyzer ) and spi settings.

  • Hi  ,

    From the interface settings you’ve shared, everything appears to be in order. One suggestion would be to experiment with changing the SPI mode to either Mode 0 or Mode 2, as this could potentially resolve the issue. It’s also evident that the Chip Select (CS) is being toggled appropriately.

    However, I would recommend conducting a thorough check of the SPI commands, ensuring they align with the specifications of the LTC2668. Additionally, it’s crucial to verify that all timing and power supply requirements are being met. These elements are often overlooked, but they play a significant role in the overall performance and functionality of the device.
