settling time, (digital) (of a linear or a multiplying digital-to-analog converter) (tsor tsd)

The time interval between the instant when the digital input changes and the instant when the analog output value enters for the last time a specified error band about its final value.

NOTE For a multiplying digital-to-analog converter, the full term and the additional subscript d must be used to distinguish between the digital and the reference settling times.
