operating temperature range, otherwise specifi cations are at T
Specifi ed as each channel (Note 6).
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 LTM4614E is guaranteed to meet performance specifi cations
over the 0°C to 125°C internal operating temperature range. Specifi cations
over the –40°C to 125°C internal operating temperature range are assured
by design, characterization and correlation with statistical process
controls. The LTM4614I is guaranteed to meet specifi cations over the full
internal operating temperature range. Note that the maximum ambient
temperature is determined by specifi c operating conditions in conjunction
with board layout, the rated package thermal resistance and other
environmental factors.

Note 3: See Application Note 100.
Note 4: The IC has overtemperature protection that is intended to protect
the device during momentary overload conditions. Junction temperatures
will exceed 125°C when overtemperature is activated. Continuous
overtemperature activation can impair long-term reliability.
Note 5: See output current derating curves for different V
Note 6: Two channels are tested separately and the specifi ed test
conditions are applied to each channel.
