TJMAX = 150°C, θJA = 110°C/ W

ELECTRICAL CHARACTERISTICS The q denotes specifications that apply over the full operating temperature

range, otherwise specifications are at TA = 25°C. VCM = 1V, VSHDN = 0.5V, VOVERDRIVE = 20mV, COUT = 10pF and for the LT1719S8

VCC = +VS = 5V and VEE = –5V, for the LT1719S6 V+ = 5V, V– = 0V, unless otherwise specified.

Consult factory for parts specified with wider operating temperature ranges.
