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. In addition to the Absolute Maximum Ratings, the
output current of the LT6107 must be limited to insure that the power
dissipation in the LT6107 does not allow the die temperature to exceed
150°C. See the applications information section “Power Dissipation
Considerations” for further information.
Note 2: Junction temperatures greater than 125°C will promote
accelerated aging. The LT6107 has demonstrated typical life beyond
1000 hours at 150°C.
ELECTRICAL CHARACTERISTICS The ● denotes the specications which apply over the full specied
operating temperature range, otherwise specications are at TA = 25°C. V+ = 12V, V+ = VSENSE+, RIN = 100Ω, ROUT = 10k, Gain = 100
unless otherwise noted. (Note 6)

Note 3: Guaranteed by the gain error test.
Note 4: Gain error refers to the contribution of the LT6107 internal circuitry
and does not include errors in the external gain setting resistors.
Note 5: The LT6107 output is an open collector current source. The
minimum output voltage scales directly with the ratio ROUT/10k.
Note 6: VSENSE+ is the voltage at the high side of the sense resistor,
RSENSE. See Figure 1.
Note 7: VSENSE(MAX) is the maximum sense voltage for which the Electrical
Characteristics will apply. Higher voltages can affect performance but
will not damage the part provided that the output current of the LT6107
does not exceed the allowable power dissipation as described in Note 1.
