Note 6: Output voltage swings are measured between the output and power supply rails. Note 7: VS = 3V, VS = ±15V GBW limit guaranteed by correlation to 5V tests. Note 8: VS = 3V, VS = 5V slew rate limit guaranteed by correlation to ±15V tests. Note 9: Minimum supply voltage is guaranteed by testing the change of VOS to be less than 250µV when the supply voltage is varied from 3V to 2.7V. The q denotes specifications that apply over the full operating temperature range. 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 the absolute maximum rating when the output is shorted indefinitely. Note 3: This parameter is not 100% tested. Note 4: The LT1632C/LT1633C 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. Guaranteed I grade parts are available, consult factory. |
