Overview
The LTC6702ITS8#TRPBF is a dual comparator from Analog Devices Inc. operating on supplies between 1.7V and 5.5V. It features a maximum guaranteed propagation delay of 500ns while drawing only 30μA maximum quiescent current per comparator. Internal hysteresis desensitizes the device to input noise, making it suitable for slow-moving signals. The CMOS inputs allow the use of large source impedances. This component is specified for an operating temperature range of –40°C to 85°C and is available in an 8-lead Plastic TSOT-23 package.
Feature Summary
- Extremely small dual comparator designed to maximize battery life while providing speed and low voltage operation
- Internal hysteresis desensitizes the device to input noise and simplifies usage with slow-moving signals
- CMOS inputs allow the use of large source impedances without affecting performance
- Rail-to-rail outputs interface directly to TTL and CMOS logic levels
Applications
- Battery Powered Systems
- Window Comparators
- Threshold Detectors/Discriminators
- Clock Regeneration
- Automotive Sensing and Controls
Procurement Notes
Verify that the ordering suffix matches the required temperature grade and packaging format. Confirm the specific part number corresponds to the desired operational range and physical footprint before finalizing procurement decisions. Ensure compatibility with existing design specifications regarding supply voltage and signal processing requirements.
Selection Notes
Select this component when board space is at a premium and low power consumption is critical. It is ideal for applications requiring fast response times within a micropower constraint. Consider its internal hysteresis for noise immunity in environments with fluctuating signals or slow-moving input voltages.
Part Context
This device belongs to the LTC6702 family of tiny micropower, low voltage dual comparators. It shares core architectural similarities with other variants in the series but differs in temperature specifications and package options. The family is engineered to provide high-speed performance alongside minimal energy draw for portable electronics.
