... During power-up, the voltage outputs rise less than 10mV above zero scale until a valid write and update take place. The power-on reset circuit resets the LTC2601-1/LTC2611-1/LTC2621-1 to midscale. The volt- age outputs stay at midscale until a valid write and update take place. ...

... Resistance from the GND pin to system star ground should be as low as possible. Resistance here will add directly to the effective DC output impedance of the device (typically 0.05Ω). Note that the LTC2601/LTC2611/ LTC2621 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 ...
