LTC6104

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 speciﬁed performance from

0°C to 70°C. The LTC6104C is designed, characterized and expected to

meet speciﬁed performance from –40°C to 85°C but are not tested or QA

sampled at these temperatures. LTC6104I is guaranteed to meet speciﬁed

performance from –40°C to 85°C. The LTC6104H is guaranteed to meet

speciﬁed performance from –40°C to 125°C.

ELECTRICAL CHARACTERISTICS The ● denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations 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 ampliﬁer A is active and ampliﬁer B is inactive, the gain

error is entirely due to the external resistors RIN and ROUT. When ampliﬁer

A is inactive and ampliﬁer 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.
