Hi TI expert

Could DAC8565 output 3 signals of 100kHz at the same time, the signal is one of sine wave, square wave and triangle wave?

Hello,

I can't see the image you attached.

The max SPI frequency is 50MHz, and each DAC update takes 24 SPI clocks. This is about 2.08MSPS.

With that you could achieve a 12-point sine wave, 12-point triangle wave, and 2-point square wave at ~80kHz. You could achieve a 9-point sine wave, 9-point triangle wave, and 2-point square wave at ~104kHz.

Best,
