1 Gain error and gain temperature coefficients are based on the ADC only, with a fixed 1.0 V external reference and a 2 V p-p differential analog input.
2 Input capacitance refers to the effective capacitance between one differential input pin and AGND. Refer to Figure 4 for the equivalent analog input structure.
3 Power dissipation measured with rated encode and 2.4 MHz analog input at –0.5 dBFS.
4 Typical specification over the first Nyquist zone.
