Note 7: Slew rate is measured in AV = – 1; input signal is ±7.5V, output measured at ±2.5V. Note 8: The LT1792AC and LT1792C are guaranteed to meet specified performance from 0 °C to 70°C and are designed, characterized and expected to meet these extended temperature limits, but are not tested at –40 °C and 85°C. The LT1792I is guaranteed to meet the extended temperature limits. The LT1792AC and LT1792AI grade are 100% temperature tested for the specified temperature range. Note 9: The LT1792 is measured in an automated tester in less than one second after application of power. Depending on the package used, power dissipation, heat sinking, and air flow conditions, the fully warmed-up chip temperature can be 10 °C to 50°C higher than the ambient temperature. Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: Typical parameters are defined as the 60% yield of parameter distributions of individual amplifiers. Note 3: Warmed-up IB and IOS readings are extrapolated to a chip temperature of 32 °C from 25°C measurements and 32°C characterization data. Note 4: Current noise is calculated from the formula: in = (2qIB)1/2 where q = 1.6 • 10 –19 coulomb. The noise of source resistors up to 200M swamps the contribution of current noise. Note 5: Input voltage range functionality is assured by testing offset voltage at the input voltage range limits to a maximum of 2.3mV (A grade), to 2.8mV (C grade).
