LTM4616
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the specified internal
operating temperature range (Note 2). TA = 25°C, VIN = 5V unless otherwise noted. Per the typical application in Figure 18. Specified
as each channel (Note 3).

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 3: Two channels are tested separately and the same testing
conditions are applied to each channel.
Note 4: See Output Current Derating curves for different V , V

A
over the 0°C to 125°C internal operating temperature range. Specifications
over the –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 specifications over the
–40°C to 125°C internal operating temperature range. The LTM4616MP
is guaranteed and tested over the –55°C to 125°C internal operating
temperature range. Note that the maximum ambient temperature
consistent with these specifications is determined by specific operating
conditions in conjunction with board layout, the rated package thermal
resistance and other environmental factors.
