* MAXIMUM CLK FREQUENCY REPRESENTS THE CLK
FREQUENCY AT WHICH A 0.1LSB SHIFT IN THE ERROR
AT ANY CODE TRANSITION FROM ITS 1MHz VALUE IS
FIRST DETECTED.
** MAXIMUM RFILTER REPRESENTS THE FILTER RESISTOR
VALUE AT WHICH A 0.1LSB CHANGE IN FULL SCALE ERROR
FROM ITS VALUE AT RFILTER = 0Ω IS FIRST DETECTED.
