TYPICAL PERFORMANCE 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.

unless otherwise specified.

Note 3. Guaranteed by design, not subject to test.

Note 4. Integral nonlinearity is defined 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:

Note 7: See Figure 4.

Note 8: See Figure 5.

Note 9: Input sampling current is the average input current drawn from the

input sampling network while the LTC2452 is actively sampling the input.

Note 10: A positive current is flowing into the DUT pin.
