Overview
The LT6703IDC-3#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 a noninverting input, open-collector output, and built-in hysteresis. It is housed in a 3-lead DFN package and specified for operation between -40°C and 85°C.
Feature Summary
- Integrates a 400mV reference with a micropower comparator
- Supports wide supply voltage range from 1.4V to 18V
- Features noninverting external input polarity
- Includes internal hysteresis for stable noise rejection
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 containing 500 pieces. Confirm the IDC designation corresponds to the industrial temperature grade of -40°C to 85°C. Ensure the DC package outline matches the required PCB footprint. Check for lead-free compliance status as per manufacturer documentation.
Selection Notes
Select this part when a noninverting threshold detection is required at approximately 400mV. Choose over the LT6703-2 if the signal source connects to the noninverting terminal. Consider the LT6703HV variants if input or output voltages exceed 18V. Verify that the 6.5µA supply current meets the power budget constraints.
Part Context
This component belongs to the LT6703 family of micropower comparators. It shares architectural similarities with the LT6703-2 but differs in input polarity. The series is designed for low-voltage applications requiring high accuracy and minimal power consumption in compact packages.

FAQ
What is the polarity of the available comparator input?
The LT6703-3 variant provides a noninverting external input, while the other internal input is connected to the 400mV reference.
Can the output handle voltages higher than the supply voltage?
Yes, the open-collector output can be referred to any voltage up to 18V independent of the supply voltage used.
