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.
Note 2: The LTC6104C is guaranteed to meet specied performance from
0°C to 70°C. The LTC6104C is designed, characterized and expected to
meet specied performance from –40°C to 85°C but are not tested or QA
sampled at these temperatures. LTC6104I is guaranteed to meet specied
performance from –40°C to 85°C. The LTC6104H is guaranteed to meet
specied performance from –40°C to 125°C.
ELECTRICAL CHARACTERISTICS The ● denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. RIN = 100Ω, ROUT = 5k, 4V ≤ +INB(VS) ≤ 60V, V
– = 0V, VREF = 2V for
VS ≥ 6V, VREF = 0.75V for VS = 4V, unless otherwise noted.

Note 3: VSENSE(MAX) is tested by applying 550mV and verifying the gain
error is less than 1%. The 1% limit is set by the accuracy of high speed
test equipment. Gain error is typically dominated by external resistor
tolerance.
Note 4: When amplier A is active and amplier B is inactive, the gain
error is entirely due to the external resistors RIN and ROUT. When amplier
A is inactive and amplier B is active, there is an additional gain error from
the LTC6104 current mirror circuit. This error term is the gain error term,
IOUT-GAINERR plus the offset error term, IOUT-OSERR.
