LT1783
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the specified
temperature range, otherwise specifications are at TA = 25°C. VS = 3V, 0V; VS = 5V, 0V; VCM = VOUT = half supply, for the 6-lead part
VPIN5 = 0V, pulse power tested unless otherwise specified. (Note 4)
