1.I would like to know what is the maximum output frequency of each channel for a 16-channel DAC DAC80516 if it outputs a 16-channel sine wave
2.If replaced with an 8-channel DAC DAC80508, will the output frequency increase?

    SPI的最大频率为50MHz。每次SPI更新需要24个时钟周期。假设每个正弦波周期需要大约24个点，则最大频率为50MHz/（24个时钟*24个点*16个通道），约为5.5kHz。
    DAC80508只有8个通道是最大频率的两倍。
