Note 1:
Stresses beyond those listed under Absolute Maximum Ratings characterized and expected to meet specified performance from –40°C to may cause permanent damage to the device. Exposure to any Absolute 85°C but is not tested or QA sampled at these temperatures. The LT6106I Maximum Rating condition for extended periods may affect device is guaranteed to meet specified performance from –40°C to 85°C. The reliability and lifetime. In addition to the Absolute Maximum Ratings, the LT6106H is guaranteed to meet specified performance from –40°C to output current of the LT6106 must be limited to insure that the power 125°C. dissipation in the LT6106 does not allow the die temperature to exceed
Note 5:
The LT6106 output is an open collector current source. The 150°C. See the applications information section “Power Dissipation minimum output voltage scales directly with the ratio ROUT/10k. Considerations” for further information.
Note 6:
VSENSE+ is the voltage at the high side of the sense resistor,
Note 2:
Guaranteed by the gain error test. RSENSE. See Figure 1.
Note 3:
Gain error refers to the contribution of the LT6106 internal
Note 7:
VSENSE (MAX) is the maximum sense voltage for which the Electrical circuitry and does not include errors in the external gain setting resistors. Characteristics will apply. Higher voltages can affect performance but will
Note 4:
The LT6106C is guaranteed functional over the operating not damage the part provided that the output current of the LT6106 does temperature range of –40°C to 85°C. The LT6106C is designed, not exceed the allowable power dissipation as described in Note 1.
