DAC8775: Will DAC8775 work with 1.8V SPI?

Hello - In the data sheet for DAC8775, the min voltage for the digital input says 2V for a logic high, is it possible for this spi interface to work at 1.8V?  If not, does TI make a 1.8V spi DAC that is multi channel and can output +/-10V and is also <10MSPS?  Thanks.

    Hi Scott,

    I would not recommend operating the device at <2V VIH.  The primary value of the DAC8775 is its adaptive power management.  If you just need a bipolar, high-voltage DAC, then please consider the DAC81408.  This device features 8 channels that can be configured for many ranges and supports 1.8V logic.

    Thanks,

    Paul
