Note 1: A heat sink may be required to keep the junction temperature below absolute maximum when the output is shorted indefinitely. Note 2: The LT1492/LT1493 are designed, characterized and expected to meet these extended temperature limits, but are not tested at – 40 °C and 85 °C. Guaranteed I grade parts are available. Consult factory. Note 3: This parameter is not 100% tested. Note 4: Guaranteed by correlation to VS = 3.3V and VS = ±15V tests. Note 5: Slew rate is measured between ±5V on an output swing of ±10V on ±15V supplies. Note 6: Most LT1492/LT1493 electrical characteristics change very little with supply voltage. See the 5V tables for characteristics not listed in the 3.3V table. Note 7: Guaranteed by correlation to VS = 5V and VS = ±15V tests. Note 8: Guaranteed by correlation to VS = 3.3V tests. |
