    Hello Machida-san,

    The PGA300 uses the same DAC output as is used in the PGA900. I recommend referencing the PGA900 datasheet for some more detailed descriptions of the characteristics of the DAC gain amplifier. www.ti.com/.../pga900.pdf

    The output error of ratiometric mode compared to absolute mode is 0.1%FSO max across temperature. There are no specific sections for absolute mode and ratiometric mode, though.

    Regards,
