DAC121S101 - Floating Input on Digital Lines?

Other Parts Discussed in Thread: DAC121S101

Hello TI,

Can you tell me if the DAC121S101 can handle a floating input on the digital input lines? Specifically interested in the DIN, SYNC, and SLKC pins.

Thanks,

Dan

Hello Dan,

Yes, you can leave the digital pins floating except for the CS pin. It should be connected high so that it cannot be accidentally pulled low, which would cause the DAC121S101 to think that it is being communicated with.
