Overview
The LMC6772BIN is a dual low-power analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 15 V and consumes only 20 µA of operating current. The device features rail-to-rail input capability and an open-drain output configuration. Key electrical specifications include a maximum input offset voltage of 18 mV, an input bias current of 0.04 pA, and a typical common-mode rejection ratio of 75 dB. It functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Dual-channel architecture with ultra-low power consumption for battery-operated applications
- Rail-to-rail input stage allowing full signal swing utilization
- Open-drain output structure facilitating flexible logic interfacing
Applications
- Battery-powered sensing systems requiring minimal quiescent current
- Threshold detection circuits in portable electronic devices
- General-purpose voltage monitoring applications
Procurement Notes
Verify the exact suffix against official Texas Instruments documentation to confirm pinout compatibility and specific performance grades. Ensure the ordering part number matches the required package type and temperature rating. Cross-reference datasheet revisions to validate electrical characteristics before finalizing procurement decisions.
Selection Notes
Select this component when low static current and wide input voltage range are critical design constraints. The open-drain output requires appropriate pull-up resistors for proper logic level translation. Consider the input offset voltage specifications relative to the precision requirements of the target application circuit.
Part Context
This device belongs to the LMC6772 family of low-power comparators. It shares functional similarities with other members of the series but may differ in specific electrical parameters such as input offset voltage or package availability. The BIN designation typically indicates a specific manufacturing bin or grade within the broader product line.
Replacement Considerations
Direct replacements include LMC6772AIMX/NOPB and LMC6772BIMX/NOPB. Verify that substitute parts match the required input offset voltage and package dimensions. Confirm that the alternative components support the same supply voltage range and operating temperature specifications.
