Timing Specifications
NOTE:
1
The initial circuit will be built using 5 V supplies for all logic and analog sections. Future circuits will allow digital operation at 3.3 V but analog operation will
remain at 5 V.
2
Conversion rate is operational down to 10 kHz without degradation in specified performance.
