ELECTRICAL CHARACTERISTICS

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

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.
