AC ELECTRICAL CHARACTERISTICS

Note 1:

All voltages are referenced to ground.

Note 2:

Note 3:

Note 4:

Full scale is user programmable. The maximum voltage that the MON inputs read is approximately full scale, even if the volt-

age on the inputs is greater than full scale.

Note 5:

Note 6:

Absolute linearity is the difference of measured value from expected value at DAC position. The expected value is a

straight line from measured minimum position to measured maximum position.

Note 7:

Relative linearity is the deviation of an LSB DAC setting change vs. the expected LSB change. The expected LSB change

is the slope of the straight line from measured minimum position to measured maximum position.

Note 8:

See the Typical Operating Characteristics.

Note 9:

is automatically the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the

before the SCL line is released.
