... U OPERATIO Power-On Reset The LTC2600/LTC2610/LTC2620 clear the outputs to zero scale when power is first applied, making system initializa- tion consistent and repeatable. For some applications, downstream circuits are active during DAC power-up, and may be sensitive to nonzero outputs from the DAC during this time. The LTC2600/ ...

... Resistance here will add directly to the effective DC output impedance of the device (typically 0.025 ), and will degrade DC crosstalk. Note that the LTC2600/LTC2610/LTC2620 are no more susceptible to these effects than other parts of their type; on the contrary, they allow layout-based performance improvements to shine rather than limiting attainable performance with excessive internal resistance ...
