LMC7211BIMX

Overview

The LMC7211BIMX is a single low-power high-voltage CMOS analog comparator manufactured by Texas Instruments. It operates with a supply voltage range of 3V to 15V and features rail-to-rail inputs and outputs, allowing signals to swing fully within the supply rails. The device offers a typical response time of 400ns and a quiescent current of 60µA per channel. It is housed in an 8-pin SOIC package and is designed for applications requiring high input impedance and wide common-mode voltage ranges.

Feature Summary

• Rail-to-rail input and output capability ensures maximum dynamic range across the full supply voltage spectrum.
• Low power consumption design supports battery-operated systems with minimal quiescent current draw.
• High input impedance CMOS architecture prevents loading effects on preceding signal sources.

Applications

• Battery-powered monitoring circuits
• Window comparators
• Threshold detection systems

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free status and RoHS compliance when ordering. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the manufacturer part number with distributor catalogs to ensure availability and correct revision levels.

Selection Notes

Select this component for designs requiring a balance between speed and power efficiency. The high input impedance makes it suitable for interfacing with high-impedance sensors. Consider the 400ns response time against application requirements; faster comparers may be needed for high-frequency switching. Verify that the 15V maximum supply voltage meets the system's power constraints.

Part Context

This device belongs to the LMC7211 family of precision comparers. It shares functional similarities with other CMOS comparers but distinguishes itself through its specific combination of low power and high-voltage operation. The family is designed to replace older bipolar comparers in modern low-power applications.

Replacement Considerations

Check for direct pin-compatible alternatives such as the LMV331 or LMH7220 if different performance characteristics are required. Verify that substitute parts maintain the same rail-to-rail input/output specifications and supply voltage ranges.
