2 years ago from the DAC datasheet:
The AD5370 has a high speed serial interface that is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards and can handle clock speeds of up to 50 MHz.
The serial word (see Table 10) is 24 bits long; 16 of these bits are data bits, six bits are address bits, and two bits are mode bits that determine what is done with the data
24 bits per channel * 32 channels = 768 bits each update 50Mhz / 768 = 65k theoretically we should be able to get a sampling frequency of 65 kHz
