LT1969 ELECTRICAL CHARACTERISTICS The ● denotes specifications which apply over the full operating temp-erature range, otherwise specifications are at TA = 25 ° C. VS = ± 2.5V, VCM = 0V, nominal mode with a 13k resistor from CTRL1 to V–and a 49.9k resistor from CTRL2 to V –, pulse power tested unless otherwise noted.

Note 9: The LT1969C is guaranteed to meet specified performance from 0°C Note 4: Thermal resistance varies depending upon the amount of PC board to 70°C. The LT1969C is designed, characterized and expected to meet metal attached to the device. θJA is specified for a 2500mm2 test board specified performance from –40°C to 85°C but is not tested or QA sampled covered with 2 oz copper on both sides. at these temperatures. Note 5: Input offset voltage is exclusive of warm-up drift. Note 10: The LT1969C is guaranteed functional over the operating temperature range of –40°C to 85°C. 4
