ELECTRICAL CHARACTERISTICS
OUT: Open-Collector Output of Comparator. This pin
provides drive for up to 40mA of load current. Off-state
voltage may be as high as 18V (36V for LT6703HV) above
GND, regardless of VS used.
GND: Ground. This pin is also the low side return of the
internal 400mV reference.
IN: External Input for Comparator. The voltage on this
pin can range from –0.3V to 18V (36V for LT6703HV)
with respect to GND regardless of VS used. The input is
noninverting for the LT6703-3/LT6703HV-3, and inverting
for the LT6703-2/LT6703HV-2. The other comparator input
is internally connected to the 400mV reference.
VS: Supply Voltage. The parts are characterized for opera-
tion with 1.4V ≤ VS ≤ 18V with respect to GND.
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: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indenitely.
Note 3: The inputs are protected by ESD diodes to the ground pin. If the
input voltage exceeds –0.3V below ground, the input current should be
limited to less than 10mA.
Note 4: The LT6703C-2/-3/LT6703HVC-2/-3, and LT6703I-2/-3/LT6703HVI-
2/-3 are guaranteed functional over the operating temperature range of
–40°C to 85°C.
The LT6703H-2/-3/LT6703HVH-2/-3, is guaranteed functional over the
operating temperature range of –40°C to 125°C.
Note 5: The LT6703C-2/-3/LT6703HVC-2/-3, are guaranteed to meet the
specied performance from 0°C to 70°C. The LT6703C-2/-3/LT6703HVC-
2/-3 are designed, characterized and expected to meet specied
performance from –40°C to 85°C but are not tested or QA sampled at
these temperatures. The LT6703I-2/-3/LT6703HVI-2/-3, are guaranteed
to meet specied performance from –40°C to 85°C. The LT6703H-2/-
3/LT6703HVH-2/-3, is guaranteed to meet specied performance from
–40°C to 125°C.
Note 6: VTH denes the threshold voltage of the comparator and combines
the effect of offset and reference accuracy.
