4 / 16 page  4 LT1886 The q denotes specifications which apply over the full operating temp- erature range, otherwise specifications are at TA = 25°C. VS = ±2.5V, VCM = 0V, pulse power tested unless otherwise noted. (Note 9) SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: The inputs are protected by back-to-back diodes. If the differential input voltage exceeds 0.7V, the input current should be limited to less than 10mA. Note 3: A heat sink may be required to keep the junction temperature below absolute maximum. Note 4: Thermal resistance varies depending upon the amount of PC board metal attached to the device. θJA is specified for a 2500mm2 test board covered with 2 oz copper on both sides. Note 5: Input offset voltage is exclusive of warm-up drift. Note 6: Slew rate is measured between ±2V on a ±4V output with ±6V supplies, and between ±1V on a ±1.5V output with ±2.5V supplies. Note 7: Full power bandwidth is calculated from the slew rate: FPBW = SR/2 πVP. Note 8: This parameter is not 100% tested. Note 9: The LT1886C is guaranteed to meet specified performance from 0 °C to 70 °C. The LT1886C is designed, characterized and expected to meet specified performance from –40 °C to 85°C but is not tested or QA sampled at these temperatures. For guaranteed I-grade parts, consult the factory. Note 10: The LT1886C is guaranteed functional over the operating temperature range of –40 °C to 85°C.
