LTC6605-10
AC ELECTRICAL CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All pins are protected by steering diodes to either supply. If any
pin is driven beyond the LTC6605-10’s supply voltage, the excess input
current (current in excess of what it takes to drive that pin to the supply
rail) should be limited to less than 10mA.
Note 3: A heat sink may be required to keep the junction temperature
below the Absolute Maximum Rating when the output is shorted
indefi nitely. Long-term application of output currents in excess of the
Absolute Maximum Ratings may impair the life of the device.
Note 4: Both the LTC6605C and the LTC6605I are guaranteed functional
over the operating temperature range –40°C to 85°C.

Note 5: The LTC6605C is guaranteed to meet specifi ed performance
from 0°C to 70°C. The LTC6605C is designed, characterized and
expected to meet specifi ed performance from –40°C to 85°C, but is
not tested or QA sampled at these temperatures. The LTC6605I is
guaranteed to meet specifi ed performance from –40°C to 85°C.
Note 6: Output referred voltage offset is a function of gain. To determine
output referred voltage offset, or output voltage offset drift, multiply V
by the noise gain (1 + GAIN). See Figure 3.
Note 7: Input bias current is defi ned as the average of the currents
fl owing into the noninverting and inverting inputs of the internal amplifi er
and is calculated from measurements made at the pins of the IC. Input
offset current is defi ned as the difference of the currents fl owing into
the noninverting and inverting inputs of the internal amplifi er and is
calculated from measurements made at the pins of the IC.
