At 0 to 1 MHz, Note 6

Note 1. Black level = Blank level = 0 mA, 0V.
Note 2. The maximum difference between the ideal (straight) conversion line and the actual conversion curve.
Note 3. The maximum difference between the ideal step size (1 LSB) and any actual step size.
Note 4. The input changes from 00h to FFh. The time from output voltage at 50% of step change to output settling (within

an error of

±1 LSB) is the full-scale settling time.

Note 5. The input changes from 00h to FFh. The output changes from 10% to 90%.
Note 6. AV

CCRT

changes within the range of 3V to 3.6V. Output voltage is measured for peak-to-peak maximum change.

PSSR is the ratio of the measurement of output at AV

CCRT

= 3.3V.
