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 LTM4608AE 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

guaranteed to meet specifi cations over the full internal operating
temperature range. The LTM4608AMP is guaranteed and tested
over the –55°C to 125°C 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.
