TIMING CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Linearity and monotonicity are defi ned from code K
2
rounded to the nearest whole code. For V
256 and linearity is defi ned from code 256 to code 65,535.
Note 3: Digital inputs at 0V or V
