*MAXIMUM ACLK FREQUENCY REPRESENTS THE ACLK FREQUENCY AT WHICH A 0.1LSB
SHIFT IN THE ERROR AT ANY CODE TRANSITION FROM ITS 2MHz VALVE IS FIRST DETECTED.
**MAXIMUM RFILTER REPRESENTS THE FILTER RESISTOR VALVE AT WHICH A 0.1LSB SHIFT
CHANGE IN FULL SCALE ERROR FROM ITS VALUE AT RFILTER = 0 IS FIRST DETECTED.
