LMV7219M7

Overview

The LMV7219M7 is a single-channel analog comparator manufactured by Texas Instruments, designed for low-voltage applications. It operates within a supply voltage range of 2.7 V to 5 V and features rail-to-rail output capability. The device exhibits a typical response time of 7 ns and includes an internal reference resistor. Key electrical parameters include a maximum input offset voltage of 8 mV, a common-mode rejection ratio of 85 dB, and a quiescent current of 1.8 mA. It supports a maximum output current of 68 mA and functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Rail-to-rail output stage enables full signal swing utilization in low-voltage systems.
• Integrated internal reference resistor simplifies circuit design and reduces component count.
• High-speed performance with a 7 ns response time suitable for fast switching applications.

Applications

• Battery-powered portable electronics requiring low supply voltage operation
• Threshold detection circuits in industrial control systems
• Signal conditioning stages in communication equipment

Procurement Notes

Verify the specific suffix 'M7' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with standard SOT-23-5 footprint requirements during PCB layout. Confirm RoHS compliance status through the manufacturer's latest datasheet revision notes before finalizing procurement orders.

Selection Notes

Select this component when a single comparator with integrated reference resistance is required. The rail-to-rail output is critical for maximizing dynamic range in low-voltage environments. Consider the 7 ns propagation delay for high-speed signal processing needs. Verify that the 2.7 V minimum supply voltage aligns with the system power architecture constraints.

Part Context

This part belongs to the LMV7219 family of micro-power comparators. It shares functional similarities with other low-voltage comparison devices but distinguishes itself through the inclusion of an internal reference resistor. The M7 suffix typically denotes a specific surface-mount package variant within the broader product line.
