... AD5024/AD5044/AD5064 DAC-to-DAC Crosstalk DAC-to-DAC crosstalk is the glitch impulse transferred to the output of one DAC due to a digital code change and subsequent output change of another DAC. This includes both digital and analog crosstalk measured by loading one of the DACs with a full-scale code change (all 0s to all 1s or vice versa) with LDAC low and monitoring the output of another DAC ...

... DIN line is clocked into the 32-bit shift register on the falling edge of SCLK. The serial clock frequency can be as high as 50 MHz, making the AD5024/AD5044/AD5064/AD5064-1 compatible with high speed DSPs. On the 32 the last data bit is clocked in and the programmed function is executed, that is, an LDAC -dependent change in DAC register contents and/or a change in the mode of operation ...

... CLR during power-on reset are ignored. The power-on reset circuit is triggered when V passes 2.6 V approximately and DD takes 50 μs to complete. No writes to the AD5024/AD5044/ AD5064/AD5064-1 should take place during this time. For applications which have a slow V ramp time (for example, DD more than 3ms recommended that a software reset command is written when the power supplies have reached their final value ...

... When accuracy is important in a circuit helpful to carefully consider the power supply and ground return layout on the board.
