Overview
The LT6700IDCB-1#TRMPBF is a micropower, low voltage dual comparator with an internal 400mV reference. It operates on supplies from 1.4V to 18V and draws 5.7µA at 1.4V. The device features open-collector outputs capable of sinking over 5mA, allowing level translation up to 18V independent of supply voltage. Input bias current is typically ±10nA. Propagation delay is 18µs (high-to-low) and 29µs (low-to-high). It is housed in a 6-lead DFN package and specified for operation from -40°C to 85°C.
Feature Summary
- Integrates two comparators with a fixed 400mV internal reference
- Open-collector outputs support load voltages up to 18V
- Includes internal hysteresis for stable output operation
- Low quiescent current suitable for battery-powered monitoring
Applications
- Battery monitor circuits
- 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 IDCB designation corresponds to the industrial temperature range (-40°C to 85°C) and the DCB6 plastic DFN package. Ensure compatibility with the required input polarity configuration for the application design.
Selection Notes
Select this variant when an industrial temperature range is required alongside low power consumption. The -1 suffix denotes one inverting and one non-inverting input, enabling window comparator functionality. Verify that the 18V maximum input/output voltage meets system requirements instead of the 36V capability found in HV variants.
Part Context
This component belongs to the LT6700 family of micropower comparators. It shares core electrical characteristics with commercial and high-temperature versions but is distinguished by its industrial grade specification. The family offers different input polarities (-1, -2, -3) and packages (SOT-23, DFN) to suit various board space and environmental constraints.
Replacement Considerations
LT6700IDCB-1#TRPBF provides identical specifications in standard tape and reel packaging.
FAQ
What is the input polarity configuration for the LT6700-1?
The LT6700-1 has one inverting input and one non-inverting input, making it suitable for use as a window comparator.
Can the output voltage exceed the supply voltage?
Yes, the open-collector outputs can be referred to any voltage up to 18V, independent of the supply voltage used.
