LMC6762BIM/NOPB

Overview

The LMC6762BIM/NOPB is a dual micro-power rail-to-rail input CMOS comparator manufactured by Texas Instruments. It features push-pull outputs and operates within a supply voltage range of 2.7V to 15V single or ±1.35V to ±7.5V dual. Key electrical specifications include a maximum propagation delay of 10µs, typical CMRR and PSRR of 75dB and 80dB respectively, and a maximum input offset voltage of 15mV at 5V. The device draws a maximum static current of 20µA and provides a typical output current of 30mA. It is housed in an 8-SOIC package with a width of 3.90mm and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Dual micro-power rail-to-rail input CMOS architecture
• Push-pull output stage capability
• Low static current consumption

Applications

• Battery-powered systems requiring low power consumption
• General-purpose analog signal comparison
• Threshold detection circuits

Procurement Notes

Verify the specific suffix designation carefully during procurement. The LMC6762BIM/NOPB denotes the tube packaging variant, distinct from the LMC6762BIMX/NOPB which uses tape and reel packaging. Confirm that the component status aligns with project requirements, as the base LMC6762BIM model is listed as obsolete. Ensure compatibility with existing PCB footprints for the 8-SOIC package before finalizing orders.

Selection Notes

Select this component when dual comparators with rail-to-rail input capabilities are required in space-constrained designs. The 8-SOIC package offers a compact solution for surface-mount applications. Consider the 10µs propagation delay and 15mV max offset voltage limits to ensure they meet the timing and accuracy requirements of the target application. Verify that the 20µA max static current fits within the system's power budget constraints.

Part Context

This part belongs to the LMC6762 series of dual comparators from Texas Instruments. It is a lead-free version (NOPB) of the LMC6762BIM. The series is designed for general-purpose applications where low power and wide supply voltage ranges are beneficial. It serves as a functional alternative to other micro-power comparators in the industry, specifically targeting cost-sensitive and battery-operated electronic devices.

Replacement Considerations

The LMC6762BIMX/NOPB is a confirmed substitute part number offering identical functionality but in tape-and-reel packaging instead of tubes.
