I have a project for Optical module 400G QSFP-DD DR4

need One laser support 4-way output so i need Idac＞400mA. 

Can AMC60304 IDAC  two channels are combined into one channel, and the output reaches 400mA??

    Hi,

    For applications that require additional current greater than the current provided by a single channel, multiple
    IDACs can be used in parallel. Multiple IDAC channels can be shorted together to produce a current that is
    equal to the sum of the individual channels. Make sure that the connected channels are enabled and disabled
    simultaneously. Avoid scenarios where a single change channel is enabled or disabled. Also make sure that
    the current being sourced by both channels is approximately the same to allow for evenly distributed heat
    dissipation.

    Regards,
