The suffix following the part number refers to the model found in the Ordering Guide section.
Measured 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, the CLK pins (CLK+, CLK−) inactive (set to AVDD or AGND).
