Overview
The LT6700CDCB-3#TRPBF is a micropower, low voltage dual comparator featuring an integrated 400mV reference. It operates on a single supply from 1.4V to 18V with typical quiescent current of 6.5µA at 5V. The device includes internal hysteresis and open-collector outputs capable of sinking up to 40mA. This specific variant provides two noninverting inputs for signal comparison against the internal reference.
Feature Summary
- Integrates a precise 400mV bandgap-derived reference to reduce component count
- Features internal hysteresis to ensure stable output operation without external components
- Open-collector outputs allow level translation and drive heavy loads such as relays or LEDs
- Supports over-the-top input voltages independent of the supply rail
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving
- Industrial control systems
Procurement Notes
Verify the suffix #TRPBF indicates tape and reel packaging. Confirm the CDCB designation corresponds to the commercial temperature grade (0°C to 70°C) and the DCB6 package type. Ensure compatibility with the required operating environment before finalizing procurement orders.
Selection Notes
Select this part when two noninverting inputs are required for threshold detection. Compare against LT6700-1 and LT6700-2 variants if different input polarities are needed. Consider the LT6700HV version if input or output voltages exceed 18V but remain within 36V limits.
Part Context
This component belongs to the LT6700 family of micropower comparators. It shares core electrical characteristics with other variants in the series, differing primarily in input polarity configuration and temperature grade. The DCB6 package offers a compact footprint suitable for space-constrained designs.
Replacement Considerations
LT6700CDCB-3#TRMPBF is available in 500-unit reels. Other temperature grades include LT6700IDCB-3 and LT6700HDCB-3. For high-voltage applications, consider the LT6700HVDCB-3#TRPBF variant.
