AD5024/AD5044/AD5064 POWER-ON RESET The AD5024/AD5044/AD5064/AD5064-1 contain a power-on reset circuit that initializes the registers to their default values and controls the output voltage during power-up. By connecting the POR pin low, the AD5024/AD5044/AD5064/AD5064-1 output powers up to zero scale. Note ...
