hi tobimc,

hier ein auszug aus dem datenblatt des oben genannten AD5398:


DATA FORMAT Data is written to the AD5398 high byte first, MSB first, and is shifted into the 16-bit input register. After all data is shifted in, data from the input register is transferred to the DAC register. Because the DAC requires only 10 bits of data, not all bits of the input register data are used. The MSB is reserved for an active-high, software-controlled, power-down function. Bit 14 is unused; Bits 13 to 4 are DAC data; Bits 9 to 0 and Bits 3 to 0 are unused.

meiner meinung nach sollte es so klappen.

sollte ich falsch liegen, bitte klärt mich auf.

gruß,

henrik
