  • Hi Sayaka,

    The easiest thing to do would be to use the gain feature in the DAC. Register 0x04 USER_GAIN allows the user to scale the output. For your case of 0 to 2 mA, if you selected the 0 to 20 mA range then the gain would be 2/20 * 65535 = 65535 --> 0x1999 hex. This would provide a scale factor of 1/10 on the output.

    Regards,
