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. V
unless otherwise specifi ed.
Note 3. Guaranteed by design, not subject to test.

Note 4. Integral nonlinearity is defi ned as the deviation of a code from a
straight line passing through the actual endpoints of the transfer curve.
Guaranteed by design and test correlation.
Note 5. Input sampling current is the average input current drawn from
the input sampling network while the LTC2453 is converting.
