Hi Liping, The difference is the package size. DAC53204W is WCSP package, and the other is QFN package. You plan to toggle the current via SPI? This will work. I think I misunderstood in your last question about the 1kHz pulse. If you want to apply this to the GPI pin to toggle the output from 10mA to 20mA then yes you can do that. This device also has a GPI pin that can be used to toggle the output. Best, Katlynne Jones
