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 n Speci ed for 40C to 125C Temperature Range impedances. n Available in Low Pro le (1mm) ThinSOT and The LTC6702 is available in the 8-pin SOT-23 and the tiny 2mm 2mm DFN Packages 2mm 2mm DFN package.
