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: 30μA/Comparator Maximum
designed to maximize battery life while providing both n
Propagation Delay: 500ns Maximum (–40°C to
speed and low voltage operation in applications where
125°C)
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 30μA maximum quiescent n High Output Drive: TTL and CMOS Compatible current. Internal hysteresis desensitizes the LTC6702 to Specifi ed at ±15mA (–40°C to 125°C), 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 n Specifi ed for –40°C to 125°C Temperature Range impedances. n Available in Low Profi le (1mm) ThinSOT™ and 2mm × 2mm DFN Packages The LTC6702 is available in the 8-pin SOT-23 and the tiny 2mm × 2mm DFN package.
