*Maximum ACLK frequency represents the ACLK frequency at which a 0.1LSB shift in the error at
any code transition from its 100kHz 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 = 0 is first detected.
