LT1816/LT1817
ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C (Note 8). 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.

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/2πVP.
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.
