fCLK = 7.2MHz
*As the CLK frequency is decreased from 2MHz, minimum CLK frequency (
error ≤ 0.1LSB)
represents the frequency at which a 0.1LSB shift in any code translation from its 2MHz value
is first detected.
Maximum CLK frequency represents the clock frequency at which a 0.1LSB shift in the error
at any code transition from its 3.5MHz value is first detected.
