LT6703IDC-2#TRPBF

Overview

The LT6703IDC-2#TRPBF is a micropower analog comparator featuring an internal 400mV reference, manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.4V to 18V and draws a typical quiescent current of 6.5μA at 5V. The device utilizes a 3-lead DFN package (2mm × 2mm) and provides an open-collector output capable of sinking over 5mA. It includes internal hysteresis of approximately 6.5mV and supports input voltages up to the supply rail or ground.

Feature Summary

• Integrates a fixed 400mV internal reference for simplified threshold detection without external components.
• Features an inverting input configuration where the external pin connects to the negative terminal.
• Supports Over-The-Top input operation, allowing signal voltages to exceed the positive supply rail.
• Provides an open-collector output stage that enables level translation to voltages independent of the supply.

Applications

• Battery-powered system monitoring
• Threshold detectors
• Window comparators
• Relay driving circuits
• Industrial control systems

Procurement Notes

Verify the specific temperature grade 'I' (-40°C to 85°C) matches the application environment requirements. Confirm the DC package footprint aligns with PCB layout constraints. Ensure the open-collector output pull-up resistor values are selected correctly for the target logic levels. Check for RoHS compliance documentation if required by regulatory standards.

Selection Notes

Select this component when low power consumption is critical alongside precise voltage monitoring. The inverting polarity suits applications where the output activates below the reference threshold. Consider the LT6703HV variants if input or output voltages must withstand potentials exceeding 18V. Evaluate the trade-off between propagation delay and supply current for timing-sensitive designs.

Part Context

This part belongs to the LT6703 family of micropower comparators, which also includes non-inverting versions and high-voltage variants. The 'DC' suffix denotes the 3-lead DFN package, while 'I' indicates the industrial temperature range. The '#TRPBF' suffix specifies tape-and-reel packaging with lead-free finish.

Replacement Considerations

LT6703IDC-2#TRMPBF offers identical electrical specifications but in cut-tape packaging instead of reel format.
