Overview
The LT6703IDC-2#TRMPBF is a micropower, low voltage comparator with an internal 400mV reference. It operates on a single supply from 1.4V to 18V and draws 6.5µA typical quiescent current. The device features an inverting input configuration with open-collector output capable of sinking over 5mA. It includes built-in hysteresis for stable operation and supports inputs up to 36V independent of the supply voltage.
Feature Summary
- Integrates a 400mV reference with an inverting comparator input
- Provides open-collector output for flexible level translation
- Includes internal hysteresis to ensure noise immunity
- Supports wide supply voltage range from 1.4V to 18V
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving
- Industrial control systems
Procurement Notes
Verify the specific suffix #TRMPBF indicates tape and reel packaging with mini-reel quantities. Confirm the IDC package designation matches the required 3-lead DFN footprint. Ensure the temperature grade 'I' aligns with the intended operating environment specifications before finalizing procurement orders.
Selection Notes
Select this part when an inverting comparator response is required relative to a fixed 400mV threshold. Choose this component for applications demanding ultra-low power consumption during active monitoring states. Consider the open-collector output capability if interfacing with logic levels distinct from the supply rail.
Part Context
This component belongs to the LT6703 family of micropower comparators. It shares architectural similarities with the LT6703-3 variant but differs by utilizing an inverting input instead of a noninverting one. The series is designed for low-voltage battery-operated devices requiring precise threshold detection with minimal power drain.

FAQ
What is the polarity of the external input on the LT6703IDC-2?
The LT6703IDC-2 features an inverting external input, while the other input is internally connected to the 400mV reference.
Can the input voltage exceed the supply voltage?
Yes, the input can range from ground to 18V regardless of the supply voltage used, supporting Over-The-Top operation.
