6104f
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 specifi ed performance from
0°C to 70°C. The LTC6104C is designed, characterized and expected to
meet specifi ed performance from –40°C to 85°C but are not tested or QA
sampled at these temperatures. LTC6104I is guaranteed to meet specifi ed
performance from –40°C to 85°C. The LTC6104H is guaranteed to meet
specifi ed performance from –40°C to 125°C.

Note 3: V
SENSE(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 amplifi er A is active and amplifi er B is inactive, the gain
error is entirely due to the external resistors R
IN
and R
OUT
. When amplifi er
A is inactive and amplifi er B is active, there is an additional gain error from
the LTC6104 current mirror circuit. This error term is the gain error term,
I
OUT-GAINERR
plus the offset error term, I
OUT-OSERR
.
