Overview
The LMC6772AIMMX/NOPB is a dual ultra-low power analog comparator manufactured by Texas Instruments. It features an open-drain output and operates within a supply voltage range of 2.7V to 15V single or ±1.35V to ±7.5V dual. Key electrical parameters include a maximum propagation delay of 4µs, typical CMRR of 75dB, and PSRR of 80dB. The input bias current is typically 400fA with a maximum offset voltage of 5mV at 5V. It functions over an industrial temperature range of -40°C to +85°C and is housed in an 8-VSSOP package.
Feature Summary
- Ultra-low power consumption with maximum 10µA supply current
- Rail-to-rail input capability for wide common-mode range
- Open-drain output configuration for flexible interfacing
- High common-mode rejection ratio ensuring signal integrity
Applications
- Battery-powered portable instrumentation
- Temperature sensing circuits
- Low-voltage threshold detection systems
- Microprocessor reset circuits
Procurement Notes
Verify the specific suffix MX indicates the VSSOP-8 package variant distinct from standard SOIC versions. Confirm RoHS compliance status as NOPB denotes lead-free and halogen-free construction. Ensure the operating environment stays within the specified -40°C to +85°C range. Check for any recent Product Change Notifications regarding assembly sites or mold compounds before finalizing procurement plans.
Selection Notes
Select this component when minimizing quiescent current is critical compared to the LMC6762 which offers push-pull outputs. The open-drain output requires external pull-up resistors, unlike push-pull alternatives. Consider the VSSOP package constraints for PCB layout if space is limited. Verify that the 4µs propagation delay meets the system timing requirements for high-speed applications.
Part Context
This device belongs to the LMC67xx family of micro-power comparators from Texas Instruments. It shares architectural similarities with the LMC6772 in SOIC packaging but utilizes a smaller VSSOP form factor. The series is designed for battery-operated applications requiring long life and low standby power consumption while maintaining adequate speed for general-purpose comparison tasks.
Replacement Considerations
LMC6772AIMX/NOPB serves as the direct pin-compatible alternative in SOIC-8 packaging. LMC6762AIMMX/NOPB offers similar power specs but provides push-pull outputs instead of open-drain.
