LTC6702IDC

Overview

The LTC6702IDC is a dual, low-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 and offers a typical propagation delay of 450ns. Key electrical specifications include a maximum input offset voltage of 3.5mV at 3V, typical CMRR of 70dB, and typical PSRR of 65dB. The maximum supply current is 64µA at 5V. It is housed in an 8-pin DFN EP package and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Dual channel configuration with rail-to-rail input and output capabilities for single-supply operation.
• CMOS process technology enabling low power consumption with minimal supply current draw.
• Automotive qualification compliant with AEC-Q100 standards for reliability.

Applications

• Automotive electronic systems requiring high-reliability signal comparison.
• Low-voltage battery-powered devices utilizing single-supply architectures.
• General-purpose analog signal processing where rail-to-rail swing is required.

Procurement Notes

Verify the specific suffix and tape-and-reel packaging designation when ordering. Confirm that the component meets the required automotive qualification standards if intended for such applications. Ensure the operating environment stays within the specified temperature range. Check for RoHS compliance status prior to integration into final assemblies.

Selection Notes

Select this component when dual comparators with rail-to-rail performance are needed in a compact footprint. It is suitable for designs constrained by low supply voltages down to 1.7V. Consider the 450ns propagation delay against system timing requirements. Evaluate the 3.5mV max offset voltage for precision needs in low-level signal detection scenarios.

Part Context

This part belongs to the LTC6702 family of low-voltage comparators from Analog Devices. It provides a dual-channel solution in an 8-lead DFN package. The series is designed for applications demanding low power and wide common-mode input ranges. It complements other single-channel or higher-speed variants in the manufacturer's portfolio.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family. Verify functional equivalence regarding rail-to-rail operation and supply voltage limits. Ensure any substitute matches the automotive qualification requirements if applicable.
