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 specified performance from –40°C to

85°C but is not tested or QA sampled at these temperatures. The LT6106I

is guaranteed to meet specified performance from –40°C to 85°C. The

LT6106H is guaranteed to meet specified 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 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 LT6106 does

not exceed the allowable power dissipation as described in Note 1.
