LT6700/LT6700HV Micropower, Low Voltage, Dual Comparator with 400mV Reference
FEATURES DESCRIPTION
n
Internal 400mV Reference
The LT®6700/LT6700HV combine two micropower, low n
Total Threshold Error: ±1.25% Max at 25°C
voltage comparators with a 400mV reference in a 6-lead n
Inputs and Outputs Operate to 36V
SOT-23 or tiny DFN package. Operating with supplies from n
Wide Supply Range: 1.4V to 18V
1.4V up to 18V, these devices draw only 6.5µA, making n
Specified for –55°C to 125°C Temperature Range
them ideal for low voltage system monitoring. Hysteresis n Low Quiescent Current: 6.5µA Typ at 5V is included in the comparators, easing design requirements n Internal Hysteresis: 6.5mV Typ to insure stable output operation. n Low Input Bias Current: ±10nA Max The comparators each have one input available externally; n Over-The-Top® Input also Includes Ground the other inputs are connected internally to the reference. n Open-Collector Outputs Allow Level Translation The comparator outputs are open collector and the output n Choice of Input Polarities: LT6700-1/LT6700-2/ load can be referred to any voltage up to 18V (36V for LT6700-3/LT6700HV-1/LT6700HV-2/LT6700HV-3 LT6700HV), independent of supply voltage. The output n Available in Low Profile (1mm) SOT-23 (ThinSOT™) stage sinking capability is guaranteed to be greater than and 2mm × 3mm DFN Packages 5mA over temperature.
APPLICATIONS
The three versions of this part differ by the polar- ity of the available comparator inputs. The LT6700-1/ n Battery-Powered System Monitoring LT6700HV-1 has one inverting input and one noninvert- n Threshold Detectors ing input, making it suitable for use as a window com- n Window Comparators parator. The LT6700-2/LT6700HV-2 has two inverting n Relay Driving inputs and the LT6700-3/LT6700HV-3 has two nonin- n Industrial Control Systems verting inputs. All versions are offered in commercial, n Handheld Instruments industrial and automotive temperature ranges. n Automotive Monitor and Controls L, LT, LTC, LTM, Linear Technology, the Linear logo and Over-The-Top are registered trademarks and ThinSOT and PowerPath are trademarks of Linear Technology Corporation.
