LMV7219M7/NOPB

Overview

The LMV7219M7/NOPB is a single-channel analog comparator manufactured by Texas Instruments, designed for low-voltage and ultra-low-power applications. It operates within a supply voltage range of 2.7 V to 5 V and features rail-to-rail output capability with a push-pull configuration. The device exhibits a typical propagation delay of 45 ns and a maximum of 20 ns, ensuring rapid response times. 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 draws a maximum quiescent current of 1.8 mA and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Rail-to-rail output stage provides full signal swing
• High-speed response with minimal propagation delay
• Operates on a single low-voltage supply

Applications

• Battery-powered portable electronics
• Threshold detection circuits
• Voltage monitoring systems
• General-purpose analog signal processing

Procurement Notes

Verify the specific suffix M7 against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperatures and supply voltages. Cross-reference ordering part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the manufacturer's latest datasheet before procurement.

Selection Notes

Select this component when low power consumption and fast response are critical in single-supply environments. The rail-to-rail output allows interfacing directly with digital logic without level shifting. Consider the input offset voltage and CMRR requirements for precision applications. Verify that the SOT-23-5 package fits the PCB layout constraints and thermal management needs of the design.

Part Context

This device belongs to the LMV7219 family of comparators from Texas Instruments, which focuses on high-performance, low-cost solutions for consumer and industrial markets. The family shares similar architectural characteristics but may vary in package options and specific electrical tolerances. The LMV7219 series is engineered to replace discrete transistor solutions in compact designs.
