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: All voltage values are with respect to GND.
Note 3: For the 8-lead PDIP , consult the factory.
Note 4: Linearity error is specifi ed 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 below GND or one diode drop above V
forward 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 tolerance, temperature variations and loading. For 5.5V < V
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 specifi cations are either correlated from 5V specifi cations or
guaranteed by design.
