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 LTM4616E is guaranteed to meet performance specifi cations
over the 0°C to 125°C internal operating temperature range. Specifi cations
over the full –40°C to 125°C internal operating temperature range are
assured by design, characterization and correlation with statistical process

controls. The LTM4616I 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: Two channels are tested separately and the same testing
conditions are applied to each channel.
