Overview
The LT6703CDC-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 the other input tied internally to the reference. It provides an open-collector output capable of sinking over 5mA, allowing level translation up to 18V independent of the supply voltage. The component is housed in a 3-lead DFN package and is specified for commercial temperature ranges.
Feature Summary
- Integrates a 400mV reference with a micropower comparator for system monitoring
- Features internal hysteresis to ensure stable operation against noise
- Open-collector output supports level translation independent of supply voltage
- Supports Over-The-Top inputs operating beyond the supply rail
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving
- Industrial control systems
Procurement Notes
Verify the specific ordering suffix #TRMPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the DC package designation matches the physical footprint constraints of the target PCB layout. Ensure the commercial temperature grade meets the operational environmental requirements of the final application design.
Selection Notes
Select this part when a fixed 400mV threshold is required for low-voltage monitoring applications. The inverting input polarity (LT6703-2) must be chosen based on whether the signal source exceeds or falls below the reference to trigger the output state change. Consider the open-collector nature of the output for necessary pull-up resistor calculations.
Part Context
This component belongs to the LT6703 family of micropower comparators manufactured by Analog Devices Inc. The series includes variants with different input polarities and extended voltage ratings. The CDC-2 variant specifically denotes the commercial temperature range and the inverting input configuration within the standard 18V operating class.

FAQ
What is the function of the external input pin on the LT6703-2?
The external input pin serves as the inverting terminal (-IN). The non-inverting terminal is internally connected to the 400mV reference.
Can the output voltage exceed the supply voltage?
Yes, the open-collector output can withstand voltages up to 18V regardless of the supply voltage used, enabling level translation.
