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: The LT4430E is guaranteed to meet performance specifi cations
from 0°C to 125°C. Specifi cations over the –40°C to 125°C operating
junction temperature range are assured by design, characterization and

denotes the specifi cations which apply over the full operating
correlation with statistical process controls. The LT4430I is guaranteed
over the full –40°C to 125°C operating junction temperature range.
Note 3: All currents into device pins are positive. All currents out of device
pins are negative. All voltages are referenced to GND unless otherwise
specifi ed.
Note 4: This parameter is guaranteed by correlation and is not tested.
