ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. V+ = 12V, VPULLUP = V+, VEN/RST = 2.7V, RIN = 100Ω,
ROUT = R1 + R2 + R3 = 10k, gain = 100, RC = 25.5k, CL = CLC = 2pF, unless otherwise noted. (See Figure 3)

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: Input and output pins have ESD diodes connected to ground. The
SENSEHI and SENSELO pins have additional current handling capability
specified as SENSEHI, SENSELO input current.
Note 3: The LT6109I is guaranteed to meet specified performance from
–40°C to 85°C. LT6109H is guaranteed to meet specified performance
from –40°C to 125°C.
Note 4: Supply current is specified with the comparator outputs high.
When the comparator outputs go low the supply current will increase by
75A typically per comparator.
Note 5: The full-scale input sense voltage and the maximum output
current must be considered to achieve the specified performance.
Note 6: Supply voltage and input common mode voltage are varied while
amplifier input offset voltage is monitored.
Note 7: Specified gain error does not include the effects of external
resistors RIN and ROUT. Although gain error is only guaranteed between
12V and 60V, similar performance is expected for V+ < 12V, as well.
Note 8: Refer to SENSELO, SENSEHI Range in the Applications
Information section for more information.
Note 9: The input threshold voltage which causes the output voltage of the
comparator to transition from high to low is specified. The input voltage
which causes the comparator output to transition from low to high is
the magnitude of the difference between the specified threshold and the
hysteresis.
