TYPICAL PERFOR A CE CHARACTERISTICS

Note 1: Absolute maximum ratings are those values beyond which the life

of a device may be impaired.

Note 2: Nonlinearity and monotonicity are defined from code 20 to code

1023. See Applications Information.

Note 4: Load is 10k

Ω in parallel with 100pF.

i.e., codes 102 and 922.

Note 6: Guaranteed by design and not subject to test.

Note 7: Measured at code 20.
