Consult LTC Marketing for parts specified with wider operating temperature ranges.
ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VCC = 11V, operating maximum VCC = 24V, no load on any outputs
unless otherwise noted.
