7 / 20 page 7 LT1815 LT1816/LT1817 181567fa ELECTRICAL CHARACTERISTICS Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: Differential inputs of ±6V are appropriate for transient operation only, such as during slewing. Large sustained differential inputs can cause excessive power dissipation and may damage the part. Note 3: A heat sink may be required to keep the junction temperature below absolute maximum when the output is shorted indefinitely. Note 4: Input offset voltage is pulse tested and is exclusive of warm-up drift. Note 5: Slew rate is measured between ±2V at the output with ±3V input for ±5V supplies and 2VP-P at the output with a 3VP-P input for single 5V supplies. Note 6: Full-power bandwidth is calculated from the slew rate: FPBW = SR/2 πVP. Note 7: This parameter is not 100% tested. Note 8: The LT1815C/LT1816C/LT1817C are guaranteed to meet specified performance from 0 °C to 70°C and are designed, characterized and expected to meet the extended temperature limits, but are not tested at –40 °C and 85°C. The LT1815I/LT1816I/LT1817I are guaranteed to meet the extended temperature limits. Note 9: Thermal resistance ( θJA) varies with the amount of PC board metal connected to the package. The specified values are for short traces connected to the leads. If desired, the thermal resistance can be substantially reduced by connecting Pin 2 of the SOT-23, Pin 4 of the SO-8 and MS8, Pin 5 of the MS10 or the underside metal of the DD package to a large metal area. Note 10: A resistor of 40k or less is required between the ISET and V– pins of the LT1815S6 and the LT1816AMS. See the applications section for information on selecting a suitable resistor.

VS = 5V, 0V; VCM = 2.5V, RL to 2.5V unless otherwise noted. For the programmable current option (LT1815S6 or LT1816A), the ISET pin must be connected to V – through 75Ω or less, unless otherwise noted. |
