PIN FUNCTIONS
INC2 (Pin 7): Input of Comparator 2. For the LT6109-1
this is the noninverting input of comparator 2. For the
LT6109-2 this is the inverting input of comparator 2. The
other comparator input is internally connected to the
400mV reference.
OUTA (Pin 8): Current Output of the Sense Amplifier. This
pin will source a current that is equal to the sense voltage
divided by the external gain setting resistor, R

SENSEHI (Pin 10): Sense Amplifier Input. The internal
sense amplifier will drive SENSEHI to the same potential
as SENSELO. A resistor (typically R
