Overview
The LTC6702CDC is a dual micropower voltage comparator manufactured by Analog Devices Inc. It features rail-to-rail inputs and outputs, operating on a single supply voltage ranging from 1.7V to 5.5V. The device utilizes CMOS process technology with a typical propagation delay of 450ns and maximum supply current of 64µA at 5V. It offers high common-mode rejection ratio (CMRR) of 70dB and power supply rejection ratio (PSRR) of 65dB. The component is housed in an 8-lead SOIC package.
Feature Summary
- Dual channel configuration with rail-to-rail input and output capabilities
- Low voltage operation supporting single supply ranges from 1.7V to 5.5V
- Micropower consumption suitable for battery-operated applications
- High noise immunity with significant CMRR and PSRR specifications
Applications
- Battery-powered portable electronics
- Threshold detection circuits
- Low voltage signal processing
- General purpose analog comparison tasks
Procurement Notes
Verify the specific suffix and package type against official Analog Devices documentation to ensure compatibility with your design requirements. Confirm RoHS compliance status and lead-free manufacturing details through authorized distributors or the manufacturer's official channels before procurement.
Selection Notes
Select this component when low power consumption and wide common-mode input range are critical. Ensure the required propagation delay meets system timing constraints, as it is not optimized for ultra-high-speed applications compared to faster comparators.
Part Context
This part belongs to the LTC6702 family of micropower comparators designed for low-voltage applications. It provides dual independent comparators in a compact package, offering a balance between power efficiency and performance for general-purpose analog signal conditioning.
Replacement Considerations
Check for direct pin-compatible alternatives such as the TS3702 or TLC3702 series if sourcing from other manufacturers. Verify electrical parameter overlaps, particularly supply voltage ranges and propagation delays, to ensure functional equivalence.
