EFFECTIVE NUMBER OF BITS (ENOB)
WORST SECOND OR THIRD HARMONIC
Measure with a low input frequency, full-scale sine wave, with approximately 5 pF loading on each output bit.
Input capacitance refers to the effective capacitance between one differential input pin and AGND.
Standby power is measured with a dc input and with the CLK± pins active (1.8 V CMOS mode).
