Overview
The LMV7255M5 is a single low-voltage comparator manufactured by National Semiconductor, housed in an SOT-23-5 package. It features rail-to-rail input capability and operates within a supply voltage range of 1.8V. Key electrical parameters include a typical Common Mode Rejection Ratio (CMRR) of 72dB and a typical Power Supply Rejection Ratio (PSRR) of 79dB. The device exhibits a maximum propagation delay of 830ns and a maximum offset voltage of 6000uV. It supports an operating temperature range from -40°C to 85°C and utilizes an open-drain output configuration.
Feature Summary
- Rail-to-rail input capability for extended signal range utilization
- Low voltage operation starting at 1.8V
- Open-drain output configuration
Applications
- General purpose comparison circuits
- Low voltage monitoring systems
- Battery-powered devices requiring minimal supply voltage
Procurement Notes
Verify the manufacturer designation as National Semiconductor or Texas Instruments, as National Semiconductor's analog division was acquired by TI. Confirm the specific suffix 'M5' corresponds to the SOT-23-5 package variant. Ensure the component meets the specified -40°C to 85°C industrial temperature range requirements for your application environment.
Selection Notes
Select this component when a single comparator with rail-to-rail inputs is required for low-voltage applications. It is suitable for designs where space is constrained due to its small SOT-23-5 footprint. Consider the 830ns propagation delay and 6000uV offset voltage limits to ensure they meet the timing and accuracy requirements of the target circuit.
Part Context
The LMV7255 is part of the LMV725x family of 1.8V low voltage comparators. This family includes variants such as the LMV7251. These devices are built using advanced Submicron Silicon-Gate BiCMOS process technology, which contributes to their performance characteristics including low power consumption and high speed relative to their voltage class.
