Overview
The LMV7219M7X is a single-channel analog comparator manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5 V. The device features a typical propagation delay of 7 ns and a rail-to-rail output stage. Key electrical parameters include a maximum input offset voltage of 6 mV at 5 V, a typical common-mode rejection ratio (CMRR) of 85 dB, and a typical power supply rejection ratio (PSRR) of 85 dB. It utilizes BiCMOS process technology and provides a push-pull output configuration.
Feature Summary
- Features a high-speed response with a typical propagation delay of 7 nanoseconds for rapid signal processing.
- Provides rail-to-rail output capability, allowing the output voltage to swing close to both supply rails.
- Operates within a low-voltage range of 2.7 V to 5 V, suitable for battery-powered applications.
- Delivers high precision with a maximum input offset voltage of 6 mV and high common-mode rejection.
Applications
- High-speed data acquisition systems requiring fast threshold detection
- Portable electronic devices powered by single-cell or dual-cell batteries
- Signal conditioning circuits in industrial control environments
Procurement Notes
Verify the specific suffix 'M7X' against the official Texas Instruments datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives if required by your manufacturing standards. Cross-reference the part number with authorized distributors to confirm current production status and availability constraints.
Selection Notes
Select this component when a single comparator with rail-to-rail output and sub-10ns speed is required. It is suitable for designs operating between 2.7 V and 5 V where low offset voltage and high CMRR are critical. Consider the SOT-23-5 package size for space-constrained PCB layouts.
Part Context
The LMV7219M7X belongs to the LMV7219 family of comparators from Texas Instruments. This series is designed for general-purpose applications requiring high speed and low voltage operation. The M7X designation typically indicates a specific tape-and-reel packaging format for automated assembly.
Replacement Considerations
LMV7219M5/NOPB: Same functional comparator in SOT-23-5 package but different reel specification. LMV7219M7X/NOPB: Identical function with NOPB indicating lead-free/RoHS compliance.
