Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: A heat sink may be required to keep the junction temperature below absolute maximum. This depends on the power supply voltage and how many amplifiers are shorted. Note 3: The LT1638C/LT1639C are guaranteed to meet 0 °C to 70°C specifications and are designed, characterized and expected to meet the extended temperature limits, but are not tested at – 40 °C and 85°C. The LT1638I/LT1639I are guaranteed to meet the extended temperature limits. Note 4: VS = 5V limits are guaranteed by correlation to VS = 3V and VS = ±15V tests. Note 5: VS = 3V limits are guaranteed by correlation to VS = 5V and VS = ±15V tests. Note 6: Guaranteed by correlation to slew rate at VS = ±15V and GBW at VS = 3V and VS = ±15V tests. Note 7: This parameter is not 100% tested. Note 8: The spec implies a typical offset voltage at VCM = 44 of 2mV and a maximum offset voltage at VCM = 44 of 5mV. |
