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.

Order Options Tape and Reel: Add #TR

Lead Free: Add #PBF

Lead Free Tape and Reel: Add #TRPBF

Lead Free Part Marking: http://www.linear.com/leadfree/

Consult LTC Marketing for parts specified with wider operating temperature ranges.

The

● denotes specifications which apply over the full operating

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

+ = 12V to 48V each channel, unless otherwise noted.

Note 2: Both V + pins (11, 20) must be connected together and both

ground pins (1, 10) must be connected together.
