LTC6702HDC#TRMPBF

Overview

The LTC6702HDC#TRMPBF is a dual micropower comparator in an 8-lead 2mm × 2mm DFN package. It operates on supplies between 1.7V and 5.5V with a maximum quiescent current of 30μA per comparator. The device features a maximum propagation delay of 500ns, internal hysteresis of approximately 4mV, and rail-to-rail CMOS outputs capable of driving TTL and CMOS loads. It supports a maximum toggle frequency of 3.2MHz and handles capacitive loads up to 10,000pF.

Feature Summary

• Micropower operation with low supply current for extended battery life
• Internal hysteresis desensitizes inputs to noise and slow-moving signals
• Rail-to-rail push-pull outputs compatible with TTL and CMOS logic levels
• CMOS inputs allow the use of large source impedances

Applications

• Battery powered systems
• Window comparators
• Threshold detectors and discriminators
• Clock regeneration circuits
• Automotive sensing and controls

Procurement Notes

Verify the specific temperature grade suffix (H) matches the required operating range of –40°C to 125°C. Confirm the DC package designation corresponds to the 8-lead 2mm × 2mm DFN form factor. Ensure the TRMPBF suffix indicates the mini tape and reel packaging configuration. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity and specifications.

Selection Notes

Select this component when board space is limited due to its compact DFN footprint. Choose this device for applications requiring low voltage operation down to 1.7V. Consider this part for designs needing built-in hysteresis to simplify threshold detection without external feedback components. Verify that the 500ns propagation delay meets the timing requirements of the target application.

Part Context

This part belongs to the LTC6702 family of tiny micropower dual comparators. It shares functional characteristics with other variants such as the LTC6702CTS8 and LTC6702IDC, differing primarily in package type and specified temperature ranges. The H suffix denotes the industrial/high-temperature grade suitable for wider thermal environments compared to standard commercial grades.
