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 LTM8048 isolation is tested at 725VDC for one second in each
polarity.
Note 3: The LTM8048E is guaranteed to meet performance specifications
from 0°C to 125°C. Specifications over the –40°C to 125°C internal
temperature range are assured by design, characterization and correlation
with statistical process controls. LTM8048I is guaranteed to meet
specifications over the full –40°C to 125°C internal operating temperature

denotes the specifications which apply over the full operating
range. The LTM8048MP is guaranteed to meet specifications over the
full –55°C to 125°C internal operating temperature range. Note that
the maximum internal temperature is determined by specific operating
conditions in conjunction with board layout, the rated package thermal
resistance and other environmental factors.
Note 4: This is the BIAS pin voltage at which the internal circuitry is
powered through the BIAS pin and not the integrated regulator. See BIAS
Pin Considerations for details.
