NOTES

1. An input voltage of 0.0 volts ±0.5 LSB should nominally correspond to the ‘011111’ to ‘100000’B transition edge.

TEST LEVELS

Level 1 - 100% production tested.

Level 2 - 100% production tested at 25°C and sample tested

at specified temperatures.

Level 3 - Sample tested only.

Level 4 - Parameter is guaranteed by design and

characterisation testing.

Level 5 - Parameter is typical value only.
