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 LT6106 must be limited to insure that the power
dissipation in the LT6106 does not allow the die temperature to exceed
150°C. See the applications information section “Power Dissipation
Considerations” for further information.
Note 2: Guaranteed by the gain error test.
Note 3: Gain error refers to the contribution of the LT6106 internal circuitry
and does not include errors in the external gain setting resistors.
Note 4: The LT6106C is guaranteed functional over the operating
temperature range of –40°C to 85°C. The LT6106C 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 LT6106H
is guaranteed to meet specifi ed performance from –40°C to 125°C.
Note 5: The LT6106 output is an open collector current source. The
minimum output voltage scales directly with the ratio R

Note 7: V
SENSE (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 LT6106 does
not exceed the allowable power dissipation as described in Note 1.
