Data format select. Low = Two’s Complement, High = Binary.
CMOS control pin that enables (SFDR MODE = 1) a proprietary circuit that may improve the spurious free dynamic
range (SFDR) performance. It is useful in applications where the dynamic range of the system is limited by discrete spurious
frequency content caused by nonlinearities in the ADC transfer function. SFDR Mode = 0 for normal operation.
