Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
VSENSE(MAX) is tested by applying 550mV and verifying the gain may cause permanent damage to the device. Exposure to any Absolute error is less than 1%. The 1% limit is set by the accuracy of high speed Maximum Rating condition for extended periods may affect device test equipment. Gain error is typically dominated by external resistor reliability and lifetime. tolerance.

The LTC6104C is guaranteed to meet specifi ed performance from
Note 4:
When amplifi er A is active and amplifi er B is inactive, the gain 0°C to 70°C. The LTC6104C is designed, characterized and expected to error is entirely due to the external resistors RIN and ROUT. When amplifi er meet specifi ed performance from –40°C to 85°C but are not tested or QA A is inactive and amplifi er B is active, there is an additional gain error from sampled at these temperatures. LTC6104I is guaranteed to meet specifi ed the LTC6104 current mirror circuit. This error term is the gain error term, performance from –40°C to 85°C. The LTC6104H is guaranteed to meet IOUT-GAINERR plus the offset error term, IOUT-OSERR. specifi ed performance from –40°C to 125°C. 6104f 3
