Overview
The LT6703CDC-3#TRPBF 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 capable of sinking over 5mA, and built-in hysteresis. It is housed in a 3-lead (2mm × 2mm) plastic DFN package and specified for operation from 0°C to 70°C.
Feature Summary
- Integrates a 400mV reference with a micropower comparator
- Supports wide supply voltage range from 1.4V to 18V
- Includes internal hysteresis for stable noise rejection
- Features open-collector output for level translation
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving
- Industrial control systems
Procurement Notes
Verify the specific suffix matches the required temperature grade and package type. Confirm that the DC package variant aligns with PCB footprint constraints. Ensure the noninverting input configuration meets circuit logic requirements. Cross-reference the datasheet revision against manufacturing specifications.
Selection Notes
Select this part when a fixed 400mV threshold is sufficient for the application. Choose the CDC-3 variant specifically for commercial temperature ranges and noninverting input polarity. Consider the HV version if input or output voltages exceed 18V. Evaluate the trade-off between the fixed reference accuracy and adjustable external resistor networks.
Part Context
This component belongs to the LT6703 family of micropower comparators. It shares architectural similarities with the LT6703-2 but utilizes a noninverting input configuration. The series includes industrial and automotive grades with extended temperature capabilities and high-voltage variants for broader operating ranges.

FAQ
What is the function of the internal reference?
The internal 400mV reference serves as the comparison threshold for the noninverting input, eliminating the need for external voltage divider components.
How does the open-collector output benefit the design?
It allows the output load to be referred to any voltage up to 18V independent of the supply voltage, facilitating level translation between different logic domains.
