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: Devices are 100% tested at 175°C to the limits shown. For normal

operating temperature range specifications, please see the LT8610A/

LT8610AB data sheet. The LT8610AX performance is based on the

LT8610AB.

The l denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C.

Note 3. The LT8610AX is guaranteed over the full –40°C to 175°C

operating junction temperature range. High junction temperatures degrade

operating lifetimes. Operating lifetime is derated at junction temperatures

greater than 125°C. The LT8610AX has no thermal shutdown.
