range.

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: All voltage values are with respect to GND.

Note 3: For the 8-lead PDIP, consult the factory.

Note 4: Linearity error is specified between the actual and points of the

A/D transfer curve.

Note 5: Total unadjusted error includes offset, full scale, linearity,

multiplexer and hold step errors.

Note 6: Two on-chip diodes are tied to each reference and analog input

which will conduct for reference or analog input voltages one diode drop

bias of either diode. This means that as long as the reference or analog

input does not exceed the supply voltage by more than 50mV, the output

code will be correct. To achieve an absolute 0V to 5V input voltage range

will therefore require a minimum supply voltage of 4.950V over initial

reference and analog input range cannot exceed 5.55V. If reference and

analog input range are greater than 5.55V, the output code will not be

guaranteed to be correct.

Note 7: The supply voltage range for the LTC1096L/LTC1098L is from

2.65V to 4V. The supply voltage range for the LTC1096 is from 3V to 9V,

but the supply voltage range for the LTC1098 is only from 3V to 6V.

Note 8: Channel leakage current is measured after the channel selection.

Note 9: These specifications are either correlated from 5V specifications or

guaranteed by design.
