The LTC®6702 is an extremely small dual comparator
designed to maximize battery life while providing both
speed and low voltage operation in applications where
board space is a premium.
These comparators operate on supplies between 1.7V and
5.5V, and have a maximum guaranteed propagation delay
of 500ns while drawing only 30μA maximum quiescent
current. Internal hysteresis desensitizes the LTC6702 to
input noise and makes it easy to use, even with slow moving signals. CMOS inputs allow the use of large source
impedances.
The LTC6702 is available in the 8-pin SOT-23 and the tiny
2mm × 2mm DFN package.

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 absolute maximum. This depends on the power supply voltage and
how many comparators are shorted. The θJA specified for the DC and
TS packages is with minimal PCB heat spreading metal. Using expanded
metal area on all layers of a board reduces this value.
Note 3: The LTC6702C and LTC6702I are guaranteed functional over
the temperature range of –40°C to 85°C. The LTC6702H is guaranteed
functional over the operating temperature range of –40°C to 125°C.
Note 4: The LTC6702C is guaranteed to meet specified performance from
0°C to 70°C. The LTC6702C is designed, characterized and expected to

meet specified performance from –40°C to 85°C but is not tested or
QA sampled at these temperatures. The LTC6702I is guaranteed to meet
specified performance from –40°C to 85°C. The LTC6702H is guaranteed
to meet specified performance from –40°C to 125°C.
Note 5: The LTC6702 comparators include internal hysteresis. The offset
voltage is defined as the average of the input voltages (trip points)
required to change the output in each direction minus VCM , while the
hysteresis voltage is the difference of these trip points.
Note 6: Output voltage swings are measured between the output and
power supply rails.
Note 7: Propagation delay is for 200mV steps, and 50mV of overdrive.
Overdrive is measured relative to the positive and negative trip points.

APPLICATIONS INFORMATION
The LTC6702 device is a fast (500ns delay), low power,
low voltage (1.7V to 5.5V supply) general purpose dual
comparator. It provides rail-to-rail outputs able to interface
to TTL/CMOS, draws low supply currents (30μA/comparator), and has internal hysteresis (approximately 4mV).
Hysteresis
Each comparator has built-in hysteresis to simplify designs,
to insure stable operation in the presence of noise at the
inputs, and to reject supply rail noise. The reference voltage
applied to the input is not the exact switching threshold
value due to the built-in hysteresis. Actual output switching
typically occurs within ±2.2mV of the reference voltage,
plus or minus the input offset voltage. External positive
feedback circuitry can be employed to increase effective
hysteresis if desired, as shown in Figure 1. This circuitry
will provide an apparent effect on both the rising and falling input thresholds (the actual internal trip points remain
unaffected). If an inverting configuration with hysteresis is
needed, simply swap the VIN and VREF connections.
Unused Inputs
Any unused inputs should be connected in a way that fixes
the output logic state high or low. One easy way to do this
is to tie +IN to V+ and –IN to GND.
Input Protection
External input protection circuitry is only needed if currents
would otherwise exceed the absolute maximum rating.
Inputs driven further negative than 100mV below ground
will not cause damage provided the current is limited to
10mA. ESD protection diodes are provided to prevent
damage during handling.
Comparator Input
The allowable input voltage ranges from 100mV below GND
to within 1.2V of the positive supply. The input may be
forced below ground without causing an improper output,
though some additional input current will begin to flow
from the ESD input protection diode. The inputs can reach
up to 6V independent of the V+ supply voltage without
causing additional input current or damage to the part.
As long as one input is within the allowable input voltage
range, the LTC6702 will continue to function normally.
Comparator Output
The comparator output is a push-pull CMOS stage
guaranteed to swing to within 350mV of V + and 250mV
of ground, over temperature when sourcing or sinking
15mA. No external pull-up/down resistor is required. To

APPLICATIONS INFORMATION
maintain micropower operation, the output stage uses a
break-before-make circuit. The break interval of this circuit
turns off both the pull-up and pull-down devices for tens
of nanoseconds before activating the appropriate output
transistor (depends on the output transition direction).
Any load connected to the output will charge or discharge
internal capacitance during this interval. This can create a
soft corner during output transitions and also decrease the
propagation delay. The Typical Performance Characteristics
section shows this behavior under three load conditions:
unloaded, 10k to ground and 200Ω to ground. Loads to
V+ have a similar affect when the output is transitioning
from low to high.
Power Supplies
at least 1mA, a 1μF bypass capacitor is recommended.
Pulsing the V+ supply to the comparators on and off may
engage the ESD protection circuitry at the V+ pin. If this
occurs, current is pulled from the V+ pin through the output
stage. Using the recommended supply bypass capacitors
with some series resistance in the V+ supply line will help
to prevent this action in pulsed supply applications.
Level Translators
The level translators in the Typical Applications section
show an adjustable high-precision voltage reference
enabling the user to vary the threshold voltage. Simply
adjusting the ratio of the two resistors changes the threshold voltage according to the following equation:
R
VTHR = 0.4 1+ F
RG
The comparator circuitry operates from a single 1.7V
to 5.5V. A 0.1μF minimum bypass capacitor is required
between the V+ pin and GND. When the output is sinking
