Overview
The LMC6772AIMM/NOPB is a dual micropower rail-to-rail input CMOS comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 15 V and draws a typical operating current of 20 µA. The device features an open-drain output configuration and is housed in an 8-VSSOP package. Key electrical specifications include a maximum input offset voltage of 8 mV, a propagation delay of up to 10 µs, and a common-mode rejection ratio (CMRR) of 75 dB. It supports a single or dual power supply and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Dual-channel architecture with rail-to-rail input capability for extended signal range utilization.
- Ultra-low power consumption design suitable for battery-operated applications.
- Open-drain output structure allowing flexible interfacing with various logic families.
Applications
- Battery-powered portable equipment requiring low quiescent current.
- Threshold detection circuits in industrial control systems.
- Signal conditioning stages in microprocessor-based monitoring systems.
Procurement Notes
Verify the specific suffix 'MM' indicates the VSSOP-8 package variant distinct from SOIC packages. Confirm RoHS compliance status via the official datasheet as manufacturing sites may vary. Ensure the ordering part number matches the exact tape-and-reel or tube quantity requirements for your assembly process. Cross-reference the manufacturer's latest lifecycle status to confirm availability before finalizing procurement plans.
Selection Notes
Select this component when rail-to-rail input compatibility is required alongside minimal power dissipation. The open-drain output necessitates an external pull-up resistor; ensure the selected resistor value aligns with the desired switching speed and load capacitance. Compare the 8 mV offset voltage against application tolerance requirements to determine if higher precision variants are necessary for specific signal integrity needs.
Part Context
This device belongs to the LMC6772 family of low-power comparators. It shares functional similarities with other members like the LMC6772AIM/NOPB but differs in packaging. The family is designed for general-purpose comparison tasks where power efficiency is prioritized over high-speed performance. It serves as a cost-effective solution for basic threshold detection in consumer and industrial electronics.
Replacement Considerations
Direct pin-compatible alternatives include the LMC6772AIM/NOPB in SOIC-8 packaging, though physical footprint differences must be accounted for. Verify that substitute components maintain the same 20 µA current draw and 2.7 V minimum supply voltage to ensure circuit compatibility without redesigning power management sections.
