LTC6702
Tiny Micropower,
Low Voltage
Dual Comparators
FEATURES DESCRIPTION
n
Low Supply Operation: 1.7V Minimum
The LTC 6702 is an extremely small dual comparator
n
Low Supply Current: 30A/Comparator Maximum
designed to maximize battery life while providing both
n
Propagation Delay: 500ns Maximum (40C to
speed and low voltage operation in applications where
125C)
board space is a premium.
n
3.2MHz Toggle Frequency
These comparators operate on supplies between 1.7V and
n
Input Voltage Range Extends 100mV Below Ground
5.5V, and have a maximum guaranteed propagation delay
n
Internal Hysteresis: 4mV
of 500ns while drawing only 30A maximum quiescent
n
High Output Drive: TTL and CMOS Compatible
current. Internal hysteresis desensitizes the LTC6702 to
Speci ed at 15mA (40C to 125C),
input noise and makes it easy to use, even with slow mov-
Capacitive Load Handling to 10,000pF
ing signals. CMOS inputs allow the use of large source
