NOTE(S):
1. Output delay time is measured from the 50% point of the rising clock edge to the 50% point of full-scale transition.
2. Output settling time is measured from the 50% point of full-scale transition to the output settling within ±1 LSB for the
Bt457/458.
3. Output rise/fall time is measured between the 10% and 90% points of full-scale transition.
