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: Applies to short circuits to ground for all split supplies and for
single supplies less than 20V. Short circuits to either supply for supplies
greater than 20V total may permanently damage the part. A heat sink may
be required to keep the junction temperature below the absolute maximum
rating when the output is shorted indefinitely.
Note 3: This parameter is not 100% tested.
Note 4: Matching parameters are the difference between amplifiers A and
D and between B and C on the LT1367/LT1369; between the two amplifiers
on the LT1366/LT1368.
Note 5: Input offset voltage match is the difference in offset voltage
between amplifiers measured at both V
CM
= V
EE
and V
CM
= V
