Overview
The LMV7239 MWC is a general-purpose analog comparator manufactured by Texas Instruments. It features ultra-low power consumption and low voltage operation with rail-to-rail input capabilities. The device offers a propagation delay of 75 ns while consuming only 65 µA at 5 V. It includes a push-pull output stage, eliminating the need for external pull-up resistors. Designed for single-supply applications, it operates within a voltage range of 2.7 V to 5.5 V. The component supports ground-sense and power-sense inputs, making it suitable for compact, battery-powered systems requiring fast response times.
Feature Summary
- Ultra-low power consumption optimized for battery-operated devices
- Rail-to-rail input common-mode voltage range extending beyond supply rails
- Push-pull output stage providing direct drive capability without external components
Applications
- Signal conditioning in industrial control systems
- Threshold detection circuits
- Battery-powered consumer electronics
Procurement Notes
Verify the specific suffix 'MWC' against official Texas Instruments documentation to confirm wafer sale status or specific package variant. Ensure compatibility with existing PCB footprints and thermal requirements. Confirm that the push-pull output configuration meets the load requirements of the target application circuit.
Selection Notes
Select this component when low power and small size are critical constraints. The rail-to-rail input allows sensing signals near ground or supply limits. The push-pull output simplifies design compared to open-drain alternatives. Consider the 75 ns propagation delay for timing-sensitive applications. Verify operating temperature range suitability for the intended environment.
Part Context
The LMV7239 belongs to Texas Instruments' LMV723x family of comparators, which includes variants like the LMV7235 (open-drain) and LMV7239 (push-pull). This family is designed for low-voltage, low-power applications. The MWC designation typically indicates a wafer-level configuration or specific manufacturing lot identifier distinct from standard tape-and-reel packages.
FAQ
Does the LMV7239 require an external pull-up resistor?
No, the LMV7239 features a push-pull output stage, which eliminates the need for an external pull-up resistor.
What is the input common-mode voltage range?
The input common-mode voltage range extends 200 mV below ground and 200 mV above the positive supply voltage, enabling ground-sense and power-sense capabilities.
