Electrical Characteristics The l denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25Â°C. V+ = 12V, VPULLUP = V+, VLE = 2.7V, RIN = 100Î©,

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 LT6119I is guaranteed to meet specified performance from

â40Â°C to 85Â°C. LT6119H is guaranteed to meet specified performance

from â40Â°C to 125Â°C.

Note 4: Supply current is specified with the comparator outputs high.

When the comparator outputs go low the supply current will increase by

75ÂµA 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.
